OPERATIONMULTIVAP 118
Type Z-Purge Bath Operation - Optional
What It Does
The Type-Z Purged system prevents ignition of flammable materials caused by contact with
electrical components inside the heating unit.
How It Works
The concept behind this purge system is to create a small positive pressure gradient inside the
bath case. By carefully sealing the heating unit or control enclosure, a small flow of clean air
or inert gas will create a slight positive pressure within the enclosure. It is important to note
that there is constant leakage out of the enclosure. In this way the enclosure is continually
purged. The pressure gradient prevents flammable vapors and occasional spills from entering
the enclosure where arcing components or high surface temperature heaters might cause
ignition. The use of an inert gas such as nitrogen enhances the technique by removing all oxy-
gen from the enclosure. By purging the enclosure for 10 minutes, the gas volume within the
enclosure is replaced multiple times ensuring that no flammable vapors remain which may have
entered while the purge system was inactive.
Operating Procedure
1. Turn on the gas flow to the Z-Purge System. Purge gas may be clean air or inert gas
such as Nitrogen. The use of Nitrogen is recommended.
2. Adjust the gas flow until 0.5 inches water pressure is maintained on the gauge
mounted on the heating unit.
3. Purge the bath for 10 minutes before engaging the electrical system.
4. After 10 minutes the gas flow may be adjusted to 0.1
5. Turn on the electrical heating unit. The purge rate must be maintained.
6. Proceed to the next section.

SAFETYMULTIVAP 118
Planning and Preparation
It is important to thoroughly understand the procedures and equipment operation prior to
the use of the equipment. High speed nitrogen evaporation requires a balance of sample
volume, nitrogen flow, bath temperature, needle position and adjustment. Improper use can
impair performance, contaminate samples or result in loss of samples. Environmental
conditions are also important, examples include hood airborne contaminates, gas purge purity,
and sample handling procedures. If you are unfamiliar with the use of the MULTIVAP System
or are working with a new procedure, it is recommended that a trial run be made using a sample
blank to determine optimal operating conditions.
The MULTIVAP System is designed to handle multiple samples simultaneously up to the
capacity of the equipment. Glass or plastic tubes from 10 to 30mm OD and up to 150mm
height may be accommodated. Centrifuge tubes, scintillation vials, and small beakers may also
be used. Choice of SS needles or disposable glass pipets (fittings) are available.
The MULTIVAP System is manufactured utilizing inert materials. FDA approved Phthalate
free tubing is used on the manifold. The black connector tube is polyurethane and internal
tubing is polyethylene, both of which are Phthalate free.
CAUTION!!!
Samples containing ether based, fuel, munitions, or other extremely flammable or
explosive materials, compounds, or residues should not be used in this equipment unless
the heating unit is equipped with the TYPE -Z Purged Intrinsically Safe Bath Option.
Even equipped with this option, extreme care and caution must be exercised when using these
materials. The equipment must be placed in a location with adequate ventilation and safe
guards, recommendations include fire suppression system, shatter proof glass, and adequate
shielding for personnel. No other electronic devices should in the same location unless they are
either Z-Purge protected or are explosion proof. No flammable solvents should be stored in this
location. Materials capable of forming peroxides prior to or during evaporation must be
stabilized with sufficient anti-oxidant or they should not be used.
Under no circumstances should this equipment be used with materials capable of auto
ignition below 150 Degrees Centigrade including materials containing peroxides.
Please Contact Organomation Associates Technical Support if you have any questions
concerning the use of TYPE-Z Purged equipment or questionable materials in OAI
equipment.

Bath Operation
5. Timed Gas and Heat Control
The Time control system allows several operating modes which can be set for different
operations. The timer may be used to preheat the bath in the morning prior to use, to
shut down the system after a specific period of time (unattended operation), or for non-
dryness endpoint operations.
Preheat Bath Timed Operation
To begin heating the bath automatically prior to use the following morning, please
follow the procedures below.
A) Turn the bath off.
B) Set the left hand timer dial to program “C”. Program C is DELAY / OPERATE
time function.
C) Set the right hand dial to 0.1H. This will allow time settings to tenths. The
three center dials may be set to the correct number of hours with the right hand
most dial representing 0.1 hours. Calculate the amount of time that will elapse
from the point the bath will be left until it will be needed the following day less 1
hour for heat up time.
Example: You leave at 5:30 PM and plan to arrive at 7:00 AM and want the
bath heated and ready to go.
Elapsed time is 13.5 hours less 1 hour for heating leaves 12.5
hours. Set the timer as follows:
0.1
C 1 2 5 H
D) Set the heat switch to timed operation
E) Set the gas switch to the middle position (OFF).
F) Turn the main power switch on.
G) Press the start switch to begin the timed countdown operation. At the
completion of the operation the bath heat will be turned on automatically.

Bath Operation (continued)
5. Timed Gas and Heat Control (Continued)
Automatic shutdown of gas or heat services - unattended operation
To shut down the bath services after a period of time during a sample evaporative run,
ideal when each sample is to be taken to dryness and the operator will not be present at
the completion of the run. Please follow the procedures below.
A) Set the left hand timer dial to program “H”. Program H is an OPERATE /
STOP time function.
B) Set the right hand dial to the time increment (seconds, minutes, hours, or tenths
of same) which is most ideal for the period necessary to process the sample.
The three center dials may be set to the correct amount of time to complete the
run. As most samples will vary slightly in their evaporative times to dryness an
addition period of time should be allowed prior to shutdown. Ten to twenty
minutes should be adequate.
Example: You wish to process 18 samples in 16 x 100mm test tubes to
dryness. Experience has shown that this takes approximately 25
minutes to complete. As you are expected in a meeting which
may take an hour or more, you should use the automatic time
system as there is no need to waste unnecessary gas flow:
Evaporation time is 25 minutes plus 10 minutes for variance, this
gives 35 minutes. Set the timer as follows:
H 0 3 5 M
C) Set the heat switch to timed operation or manual to bypass timed control.
D) Set the gas switch to the timed position.
E) Follow instrument instruction procedures for flow meter and needle valve
settings.
F) Press the start switch to begin the timed countdown operation. At the
completion of the operation the gas flow will be turned off automatically.
NOTE: To stop a timed run at any point simply push the reset switch.

Bath Operation (continued)
5. Timed Gas and Heat Control (Continued)
Non-dryness automated endpoint - unattended operation
The MULTIVAP system may be used for timed non-dryness endpoint evaporation. In
order for this operation to be successful the following parameters must be maintained.
Test Tube Size - All tubes must be the same size
Sample Volume - All sample volumes must be equal
Gas Flow Rate - Must be the same per sample / per position / per run
Bath temperature - The same set point must be used for each run
A trial run must be made to determine the time required to obtain the specific endpoint
desired. Careful notes should be maintained on all operating conditions. Sample size,
volume, and gas flow are the most critical, with gas flow being the most difficult to
control. Please follow the procedures outlined in the previous section for operation of
the timed system with unattended operation and shut down.
The following procedures will help to improve accuracy for each run.
A) Set the pressure regulator to a position high enough to meet all flow require-
ments 20 - 30 PSIG should be sufficient for most applications.
B) Open each row with toggle switch
C) Gas flow to each position should be increased to 0.5 LPM / Position.
D) Samples should be equally distributed around the bath.
E) Maintain a log of all operating conditions and positions for future use.
Experimentation has demonstrated that evaporation rate at a given temperature range is largely a
function of gas flow rate, 92%. Minor fluctuation in temperature +/- 2 degrees Celsius have
little impact on rate, less than 8%. At endpoint, evaporative losses by heat alone are negligible
for short periods of time, 10 - 30 minutes, except for very volatile compounds.
