- Application of pressure (Figure 11: Application of pressure)
The sample solenoid valve opens the micro valve for the gas sample with carrier
gas and applies a control pressure of 5.5 bar. The micro solenoid valve is blocked
and a defined sample volume is enclosed in the sample loop. The switching sole-
noid valve regulates the pressure in the sample loop with carrier gas.
