(5) Analyzer Base Sampling Unit (GCSMP)

In order to ensure the process gas chromatograph operates stably over a long period of time, it

is necessary to select the most appropriate sampling system corresponding to sample properties

in addition to analyzer stability and reliability. The GCSMP can be equipped on the self-standing

GC8000 Type 1 and 2, in which the analyzer and GCSMP can be operated and maintained

integrally.

The GCSMP adjusts the pressure and ﬂ ow rate of the measurement stream for measuring the

process sample (gas and liquid) and the calibration and validation stream with standard gas

(liquid). The GCSMP also has a humidifying and warming function (setting temperatures: 50°C

or 75°C) and stream switching function by using air output from the analyzer. If the GCSMP is not

equipped, the stream switching valve can be operated by sending the air output or contact output

to an external sampling system.
