1Introduction

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.

2Site Requirements and Specifications

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

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.
