Introduction to the Micro Vacuum Degasser
Introduction to the Micro Vacuum Degasser
The Agilent 1260 Infinity micro vacuum degasser, model G1379B,
comprises a 4- channel vacuum container, including 4 micro structured
membranes, and a vacuum pump. When the micro vacuum degasser is
switched on, the control circuit turns on the vacuum pump, which is
operated with constant speed and voltage generates a partial vacuum in
the vacuum container. The pressure is measured by a pressure sensor. The
micro vacuum degasser maintains the partial vacuum with the help of a
controlled leak in the degasser’s proportional valve and by varying size of
the controlled leak within the proportional valve, depending on the signal
from the pressure sensor.
The LC pump draws the solvents from their bottles through the special
plastic membranes of the vacuum container. As the solvents pass through
the vacuum chambers any dissolved gas in the solvents permeates through
the membranes into the vacuum container. The solvents will be almost
completely degassed when leaving the outlets of the micro vacuum
degasser.

Site Requirements
A suitable environment is important to ensure optimal performance of the
instrument.
Power Considerations
The module power supply has wide ranging capability. It accepts any line
voltage in the range described in Table 1 on page 11. Consequently there
is no voltage selector in the rear of the module. There are also no
externally accessible fuses, because automatic electronic fuses are
implemented in the power supply.
WARNING
Hazard of electrical shock or damage of your instrumentation
can result, if the devices are connected to a line voltage higher than specified.
➔Connect your instrument to the specified line voltage only.
WARNING
The module is partially energized when switched off, as long as the power cord is
plugged in.
Repair work at the module can lead to personal injuries, e.g. electrical shock, when
the cover is opened and the module is connected to power.
➔Always unplug the power cable before opening the cover.
➔Do not connect the power cable to the instrument while the covers are removed.

Site Requirements and Specifications 2
Site Requirements
Power Cords
Different power cords are offered as options with the module. The female
end of all power cords is identical. It plugs into the power- input socket at
the rear. The male end of each power cord is different and designed to
match the wall socket of a particular country or region.
CAUTION
Inaccessible power plug.
In case of emergency it must be possible to disconnect the instrument from the power
line at any time.
➔Make sure the power connector of the instrument can be easily reached and
unplugged.
➔Provide sufficient space behind the power socket of the instrument to unplug the
cable.
WARNING
Absence of ground connection or use of unspecified power cord
The absence of ground connection or the use of unspecified power cord can lead to
electric shock or short circuit.
➔Never operate your instrumentation from a power outlet that has no ground
connection.
➔Never use a power cord other than the Agilent Technologies power cord designed
for your region.
WARNING
Use of unsupplied cables
Using cables not supplied by Agilent Technologies can lead to damage of the
electronic components or personal injury.
➔Never use cables other than the ones supplied by Agilent Technologies to ensure
proper functionality and compliance with safety or EMC regulations.

2Site Requirements and Specifications
Site Requirements
Bench Space
The module dimensions and weight (see Table 1 on page 11) allow you to
place the module on almost any desk or laboratory bench. It needs an
additional 2.5 cm (1.0 inches) of space on either side and approximately
8 cm (3.1 inches) in the rear for air circulation and electric connections.
If the bench shall carry a complete HPLC system, make sure that the
bench is designed to bear the weight of all modules.
The module should be operated in a horizontal position.
Condensation
WARNING
Unintended use of supplied power cords
Using power cords for unintended purposes can lead to personal injury or damage of
electronic equipment.
➔Never use the power cords that Agilent Technologies supplies with this instrument
for any other equipment.
CAUTION
Condensation within the module
Condensation will damage the system electronics.
➔Do not store, ship or use your module under conditions where temperature
fluctuations could cause condensation within the module.
➔If your module was shipped in cold weather, leave it in its box and allow it to warm
slowly to room temperature to avoid condensation.

Damaged Packaging
Upon receipt of your micro vacuum degasser, inspect the shipping
containers for any signs of damage. If the containers or cushioning
material are damaged, save them until the contents have been checked for
completeness and the micro vacuum degasser has been mechanically and
electrically checked. If the shipping container or cushioning material is
damaged, notify the carrier and save the shipping material for the carriers
inspection.
Delivery Checklist
Ensure all parts and materials have been delivered with the micro vacuum
degasser. The delivery checklist is shown below. To aid in parts
identification, please see “Parts and Materials for Maintenance” on

Optimizing the Stack Configuration
Optimizing the Stack Configuration
If your micro vacuum degasser is part of a system, you can ensure
optimum performance by limiting the configuration of the system stack to
the following configuration. This configuration optimizes the system flow
path, ensuring minimum delay volume (from point of solvent mixing to
head of column) and dead volume (from point of injection to detector
outlet).

NOTE
In an Agilent 1260 Infinity stack, the individual modules are connected through a CAN
cable. The Agilent 1260 Infinity micro vacuum degasser is an exception. The micro vacuum
degasser can be connected via the APG remote cable to the other modules of the stack. An
Agilent 1260 Infinity Instant Pilot can be connected to the CAN bus at any of the modules in
the system except for the degasser. The control software can be connected to the system
through one GPIB or LAN cable (via LAN-Card) at any of the modules (except for the
degasser), preferably at the detector.
