Carrier gas

He, Ar

Notice:

The carrier gas defined for the delivered state must be used.

Changing the carrier gas could destroy the thermal conductivity detectors.

• Gas purity (minimum requirement)

? 99.999 % (5.0)

• Solid components

< 0.1 ?m

• Required filtration

Degree of separation 99.99 % for 0.1 ?m particles

• Consumption

• Inlet pressure

600 kPa (g) recommended

Important:
A continuous carrier gas supply is required for error-free operation (frequent carrier gas failure has a negative effect on the service life of the detectors and the device-internal pressure regulator). In addition, an external two-layer pressure regulator for the carrier gas pressure is strongly recommended.
