1 The purity of the hydrogen gas produced by the VWR Hydrogen Generator is in excess of 99.99998%.
The VWR 89209-862 and 89209-864 Hydrogen Generators are completely engineered
systems designed to produce ultra-pure1, dry hydrogen gas from deionized water and elec-
tricity. The hydrogen generator utilizes the principle of electrolytic dissociation of water and
subsequent diffusion through a palladium membrane to generate ultra-pure hydrogen gas.
The outlet pressure of the hydrogen generator is adjustable, and the generator can deliver
hydrogen at pressures up to 60 psig (4.1 barg). The 89209-862 has a hydrogen delivery
capacity of 150 cc/min., and the 89209-864 has a hydrogen delivery capacity of 300 cc/min.
The high quality of the hydrogen produced by the VWR Hydrogen Generators makes them
a valuable addition to the analytical laboratory. The generators are ideal for use with high
sensitivity Flame Ionization Detectors (FID’s), Thermal Conductivity Detectors (TCD’s), Trace
Hydrocarbon Analyzers, and air pollution monitors. The ultra-pure hydrogen produced by the
Parker Balston Hydrogen Generator may also be used to replace helium as a carrier gas in
many GC applications.
The VWR 89209-862 and 89209-864 Hydrogen Generators incorporate all the components
necessary to convert deionized water into ultra high purity hydrogen gas using a nominal
amount of electricity. The key operating components of the hydrogen generators are the
electrolytic cell, the palladium membrane, and the pressure controller (see Flow Schematic,
Figure 2).
The electrolytic dissociation of water to produce hydrogen and oxygen takes place in the
electrolytic cell of the VWR Hydrogen Generator. The operational components of the cell are
the anode and cathode. The anode is nickel. The cathode is palladium, formed into tubes.
(See “Palladium Membrane” section below for further details.) The electrolysis reaction:
H2O H2 + (1/2)O2
takes place in the cell as electricity passes through the deionized water. During electrolysis,
oxygen and other impurities collect at the annode and are subsequently vented from the gen-
erator. Hydrogen ions collect at the cathode and pass through the palladium tubes, driven by
the applied electric potential. Inside the palladium tubes, the hydrogen recombines to form
puried molecular hydrogen. The newly formed, ultra-pure hydrogen is under pressure and
ready to deliver, in a controlled ow, to the required usage point.
The palladium membrane consists of bundles of palladium tubes. Because of its small atomic
size, only hydrogen and its isotopes can pass through the palladium membrane; therefore,
the hydrogen produced by the Parker Balston Hydrogen Generator is ultra-pure.
The hydrogen pressure at the outlet is regulated by an electronic pressure control circuit.
A pressure transducer monitors the hydrogen pressure at a point between the cell and the
outlet of the hydrogen generator. The control circuit adjusts the electrical current to the cell as
needed to maintain the hydrogen set pressure.
The VWR Hydrogen Generator has been certied to IEC 1010 Standards (CSA 22.2
No.1010.1-92) and UL standards (UL 3101-1). The generators bear the CSA and UL safety
markings on the product label.
Note: Generators rated for 230 VAC service, carry the CE mark in addition to the CSA and
UL marks.

The VWR Hydrogen Generators have a congurable display on the front panel. Both lan-
guage and pressure units can be selected by the user, by pressing the
button located under the top access panel as shown in gure 4. To congure the
display:
Press and hold the button to scroll through the lan-
guage options. When the required language is displayed, release the button to select
that language.
Following the language selection, pressure units can be selected. Press and hold the
button to scroll through the pressure unit options.
When the required pressure units are displayed, release the button to select the units.
Pressure units can only be changed after selecting a language.
The VWR Hydrogen Generators have been designed with great attention to safety. The key
safety features include: minimal hydrogen storage capacity (only 50 ml), a hydrogen pro-
duction control circuit, an electrolyte leak detector, an over temperature sensor, a pressure
sensor, and a low water shut-off control (see Figure 2). As a result of the minimal storage
capacity and other safety features (detailed later in this text), the Parker Balston Hydrogen
Generators comply with OSHA hydrogen safety requirements.
The VWR Hydrogen Generators have built-in system diagnostics that monitor the operation
of the generator and display its operational status to the user. When the system is operating
normally, the display will be shown as in Figure 3. If a system fault occurs, the display will
indicate the error and the current operating pressure. See Figure 3 for an explanation of the
error messages.

If the electrolytic cell exceeds its maximum temperature safety setpoint, the generator will
shut down until the cell cools. When the generator shuts down as a result of excessive cell
temperature, the "High Temperature" message will be displayed.
If the hydrogen supply line is over pressurized, the generator will shut down. When the
generator shuts down as a result of excessive pressure in the hydrogen supply line, the “High
Pressure” message will be displayed.
If the water supply in the feed water bottle reaches a preset level (3-1/2 day supply), the
“Add Water” message will be displayed and a slow, audible signal will sound. The system
remains operational. The signal will be reset when the water bottle is relled above the “Add
Water” mark.
If the deionized water supply in the feed water bottle reaches the preset level,
the “Low Water” message will be displayed, and the hydrogen generator will shut down. A
rapid, audible signal will sound when the minimum water condition occurs. The generator will
re-start and the audible signal will be reset as soon as deionized water is added and the water
level rises over the “Low Water” level mark. The VWR Hydrogen Generator will run for 8-10
days (depending on ambient temperature, ow demand, etc.) at maximum ow on a full water
bottle, before the “Add Water” message will be displayed.
The internal circuitry of the VWR Hydrogen Generator controls the electrolytic cell current to a
safe level, eliminating the possibility of excessive hydrogen production.
If electrolyte solution should pass through the system into the hydrogen output stream, the
“Check Cell” message will be displayed and the outlet solenoid valve will close, preventing
damage to equipment installed downstream from the VWR Hydrogen Generator.

Installation
The VWR 89209-862 and 89209-864 Hydrogen Generators are free-standing bench-top
units.
The generator should be located indoors, protected from
severe weather conditions, and free from excessive ambient dust or dirt.
The ambient temperature of the air surrounding the generator must be
between 50°F and 104°F (10°C and 40°C). Place the hydrogen generator in an upright posi-
tion, on a level surface, in close proximity to both the electrical power supply and the equip-
ment requiring the hydrogen supply.
The VWR Hydrogen Generator weighs 58 lbs. (26 kg.) Use proper equipment and lifting
techniques for transporting this equipment to its installation location. The hydrogen genera-
tor is intended to remain stationary when lled with water and electrolyte. If necessary, the
generator may be relocated over distances when lled.
Lift the generator by the metal case only. The
generator should remain upright when moved. For long distance moves, the generator must
be shut down and drained. (See Shutdown section of this manual.)
The VWR Hydrogen Generator may be operated by a 120 VAC or a 230 VAC, 50/60
Hz power supply.
See product label on the rear panel of the hydrogen gen-
erator for factory voltage setting. To connect the generator to the power supply, simply plug
the female end of the electrical cord into the receptacle on the right side of the generator, and
the opposite end into a three-pronged earthed power receptacle.
The VWR Hydrogen Generator must be supplied with deionized water on
a regular basis. The water should be 5 Megohm-cm, or better quality deionized water.
The outlet connections for the VWR Hydrogen Generators are a 1/8” compression
tting. All tubing and ttings downstream from the hydrogen generator should be clean stain-
less steel to minimize contamination of the hydrogen stream. If copper tubing has been used
with hydrogen in the past and has yielded acceptable results, there is no need to alter an
existing piping conguration to install the VWR Hydrogen Generator. The piping congura-
tion for the hydrogen delivery system should include a means for venting subpurity hydrogen
generated during system warm-up. This may also be accomplished by disconnecting the
downstream instruments.
VWR strongly recommends the installation of a shutoff valve and pressure regulator at the
process or instrument being supplied with hydrogen from the generator. (If the process or
instrument has its own internal shutoff valve and pressure regulator to isolate it from the
hydrogen line, this installation is unnecessary.)

For convenience, the hydrogen stream from the VWR Hydrogen Generator is manifolded for
carrier and fuel gas applications. There is no difference in hydrogen quality between the two
ports. The generator is shipped with a 1/8" ferrule tting on the fuel gas port and a pipe plug
on the carrier gas port. If hydrogen is being used as a carrier gas, simply remove the pipe
plug from the carrier port and replace with the nut and ferrule supplied in the accessories bag.
The combined ow from the car-
rier and fuel gas ports must not exceed the capacity of the generator.

Parker recommends venting the oxygen port on the generator to the room. If the exhaust
from the generator must be piped to an exhaust hood, the line from the generator exhaust
should have a continuous upward or downward slope. Piping in this manner will prevent po-
tential damage to the cell resulting from backpressure buildup in the exhaust line.

Figure 6- External Water Fittings
for Gravity or Pressure Feed
The water tank should be maintained above the rell level. If the water level becomes too low
the generator will automatically shut down. Additionally, the water quality should have an ini-
tial resistivity of greater than 5 meg-ohms/cm. If the water quality is insufcient, the generator
will not perform to its specications.
You may be using one of these three methods of supplying water to the generator:
• Use Parker Balston HydroGenMate or an external pressurized source, for automatic
water feed
• Manually lling tanks
• Gravity feed from an external reservoir
Follow the directions below that apply to the method that you are using.
For manual water feed installations, no plug/tting is required for the water feed port.
1. Unscrew the ll cap on the water tank at the rear of the unit.
2. Fill the tank with deionized water until the water is at the "FULL" line.
Note: Follow "Preparation" instructions on rst time startup.
Caution: Do not overll the water tanks. The water level should be kept below the port on
the top inside of the tank.
1. With the round external water tting connected to the Water Inlet Port on the back of
the generator (see Figure 6), ll the external reservoir with deionized distilled water. The
"external water insert" is supplied with a length of Tygon™ tubing for connection to the
reservoir.
2. Check to make sure that the water level in the generator is initially steady at the "WA-
TER FULL" line.
When connected to a pressurized water source (maximum pressure is 50 psig), you must use
a recirculating loop at the generator to ensure that only fresh deionized, distilled water is used.
1. With the hexagonal external water tting connected to the Water Inlet Port on the back
of the generator (see Figure 6), connect the generator to the pressurized source and turn
on the water supply. The "external water insert" is supplied with a length of Tygon™ tub-
ing for connection to the water source.
2. Check to make sure that the water level in each tank in the generator is initially steady
at the "FULL" line. Approximately four liters of water are required to completely ll the
generator.

To maximize the life of the palladium membrane, the VWR Hydrogen Generator should be
run continuously. If the hydrogen generator must be shut down for short periods of time (e.g.,
overnight), leave the power switch in the “on” position, and move the hydrogen output switch
to the “OFF” position. Shutting the unit down in this manner will minimize water and energy
consumption.
!
The hydrogen delivery pressure may be adjusted using the pressure
adjust knob located beneath the access panel on the top of the generator (see Figure 4).
During pressure adjustment, LCD display will show the pressure setting and the “Set Pres-
sure” message will be displayed. After approximately 20 seconds of pressure adjustment, the
digital pressure display will automatically switch to display the actual system pressure, and the
message will change to “Output Pressure”.
The hydrogen outlet valve is controlled by a switch located beneath the ac-
cess panel on the top of the generator. To open the outlet valve and initiate ow, simply press
the switch to the “AUTO” position. While operating in the “AUTO” position, the hydrogen out-
let valve will remain open. If a fault in the operation of the system occurs, a system diagnostic
message will show on the front panel and the hydrogen valve will be automatically controlled.
For temporary shutdowns, move the switch to the “OFF” position. When the switch is closed
in this manner, the generator will maintain its internal pressure. The valve should remain in
the “AUTO” position for normal operation. The “ON” position will override the controls to allow
for troubleshooting.
Set the hydrogen pressure adjust knob to the desired output pressure and set the hydrogen
output switch (see Figure 2) to the “AUTO” position. The solenoid valve will then open. Using
a ow controller or needle valve, set the warmup ow to 80-85% of the total generator capac-
ity. Open the downstream vent valve(s) to purge the lines (see Figure 5). Hydrogen output
will begin approximately 10 minutes after powering the unit on, and will increase to its rated
capacity and purity in 2 to 4 hours. Over this period of time, the cell will warm up and all pip-
ing will be purged to prepare for high purity hydrogen delivery.
After the generator has warmed up (2 hours minimum) and the lines have been purged,
connect the piping to the instrument or process which requires high purity hydrogen. Allow
pressure to build in the line before initiating ow through the instrument or process. The digi-
tal pressure displayed slowly increases until the hydrogen lines reach the set pressure. The
amount of time required to ll the line is dependent on the length and diameter of the piping
used.
The quality of the delivered hydrogen gas depends on the cleanliness of the delivery
lines and accessories, both internal and external to the Parker Balston Hydrogen Generator.
Leaks, traces of moisture, air, reducible oxides, and other contaminants must be ushed out
of the system before the purity of the delivered hydrogen meets specications.
On a regular basis, monitor the water level and operational status. After the
initial 48 hours of operation, ll the generator with deionized water ,
on an as needed basis, lling until the level indicator on the front panel is at or slightly beyond
the “WATER FULL” level. Monitor the hydrogen consumption of the down-
stream equipment to ensure ow is within the capacity of the generator (i.e., 150 cc/min. for
the 89209-862, and 300 cc/min. for the 89209-864).
It is not unusual for a faint mist to vent from the generator vent port during operation.
If there is a power interruption during operation, the generator will power up with the hydro-
gen output valve switch in the "ON" position when power is restored. If the built-in system
diagnostics trigger a fault message, consult the Troubleshooting and Service section of this
manual for further instructions.

Maintenance
To re-start the VWR Hydrogen Generator after a temporary shutdown, switch the hydrogen
outlet valve to “Auto”, set the hydrogen output pressure to the desired reading, and adjust
the ow using the (customer-provided) ow control device. If the cell has cooled during the
shutdown period, the hydrogen generator will require 2 to 4 hours to achieve its specied
hydrogen ow rate.
If the VWR Hydrogen Generator is being shut down for shipment or for storage for an extend-
ed period, then the system must be drained and plugged. Instructions for long term shutdown
and plugs may be requested from VWR.
The primary maintenance activities required by the VWR Hydrogen Generator are lling the
feed water bottle and changing the electrolyte solution. If necessary, the VWR Hydrogen
Generator may be wiped clean with a dry cloth on an as needed basis. Do not use water,
aerosols, or other cleaning agents to clean the unit. Use of any liquid detergent to clean the
generator could present an electrical hazard.
If the VWR Hydrogen Generator is operated 24 hours per day at its rated maximum ow rate,
the water in the feed water bottle should last for 8 to 10 days. VWR recommends check-
ing the water consumption rate on a routine basis until a lling schedule can be established.
(Note: If auto water ll is used this is not necessary.) Ambient temperatures will affect water
consumption, and these conditions should be taken into consideration when planning a rell
schedule for the hydrogen generator.
As needed, slowly rell the water reservoir with deionized water, using a funnel, to the “WA-
TER FULL” mark. Do not overll. Use deionized water with a rating of or bet-
ter. Failure to use a funnel may result in spills and subsequent damage to the generator (see
Caution on page 7 in the Utilites section). If the water supply is depleted beyond the rell
level, the “Add Water” message will be displayed and the hydrogen generator will generate an
audible signal.
If the water is not relled before it drops to the minimum level, the “LOW WATER” message
will be displayed and the system will safely shut down and a more rapid audible signal will
sound.
The electrolyte solution must be changed once each year to maintain efcient operation of
the hydrogen generator. If the electrolyte is not changed at this interval, the gradual forma-
tion of sodium carbonate (Na2CO3) and the contamination of the electrolyte by trace impurities
in the deionized water could adversely affect the operational characteristics and life of the
electrolytic cell.
The electrolyte is a specially prepared solution of sodium hydroxide and may be
dangerous if handled improperly.

If the cell is drained too soon after shutdown,
the hydrogen which saturates the palladium membrane will be released too quickly and will
react with the oxygen in the air. This is a vigorous reaction which will heat the palladium and
permanently damage the cell.
Eye protection and neoprene or butyl gloves (see warning notice above.)
One bottle of Parker Balston Electrolyte Solution (P/N 920071).
Phillips head screwdriver, polyethylene catch basin (3-5 liter capacity), and
funnel.
The procedure for changing the electrolyte is as follows:
1 Turn off the VWR Hydrogen Generator, disconnect it from the power supply, and allow
it to cool for four hours, preferably overnight. Remove the back panel from the unit by
removing the four panel screws.
2 Open electrolyte solution. Remove water ll cap from generator and insert funnel.
3 Remove the drain valve assembly from its holder and open the drain valve to empty con-
tents to the catch basin. Close the drain valve when draining is complete. Quickly replace
the drain assembly into its holder.
4 , pour one bottle of Electrolyte Solution (P/N 920071) into the generator
through the funnel.
5 Fill the generator with deionized water, until the level indicator on the front panel is 1"
below the “WATER FULL” level (approximately 3 liters), as detailed in Preparation section
(page 7) of this manual. Do not overll.
6 Restart the generator following the instructions detailed in the Start-up section of this
bulletin (page 6). Allow 2 to 4 hours for generator to reach ow and pressure specica-
tions. During the rst 48 hours of operation, add deionized water, if needed, lling only
until the level indicator is 1" below the “WATER FULL” level.
Occasionally, one or both of the fuses in the generator may burn out. The fuses are located
in the power receptacle on the left hand side of the generator.
Both fuses should be checked each time fuse replacement
is warranted. To access the fuses, use a small screwdriver to remove the holder located in
the power receptacle of the generator. Replace either one or both fuses as necessary and
re-assemble.
