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.
Figure 1 Overview (only one of the four solvent channels is shown)

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 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.

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 Unaccessable 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.

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 should carry an Agilent 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.
