3.6 Analysis process

The following four diagrams Figure 10: Flushing (default position), Figure 11: Ap-

plication of pressure, Figure 12: Injection and Figure 13: Analysis show the basic

analysis sequence. The process is only shown for one channel for the purpose of

simplification.

- Default position

Carrier gas (green)

is connected to the injector via a solenoid valve with a pres-

sure of 5.5 bar. It applies pressure to the micro valves for the injection and

gas

sample, whereby they are closed (red). The pressure-regulated carrier gas flows

continuously over flow resistors through the analysis and reference column.

- Flushing (Figure 10: Flushing (default position))

The solenoid valve for the gas sample is switched to ventilation, the pressure at

the micro valve is relieved and the valve opens. The gas stream flows through the

sample loop. Continuous flushing that is always activated takes place at the PGC

9300.
