Gas Sampling Valve Overview

A valve for the automatic sampling of gas is available with the FOCUS GC.
The valve is installed behind the injector/detector compartment of the GC. The
valve is not heated.
For the automatic gas sampling, a 6-port valve is used. A wide range of sampling
loops allows the analysis of different sample volumes.
NOTE A sampling loop with 1 mL of volume is provided in the standard outfit.
The sampling loop is installed directly on the valve. The switching between load
sample and inject sample position (and vice-versa) is controlled through the
FOCUS GC keypad or through the GC method created with the data system.
To install/replace the sampling loop, please refer to the chapter
