3 Gas chromatograph PGC 9300
The Process Gas Chromatograph PGC 9300 analyzes natural gas and biogas and
determines the quantities of individual components of these gases from which the
energy content, compressibility factor and other parameters can be calculated in
an additional, separate evaluation unit. This other, separate evaluation unit is the
GC 9300, which determines the course of the analysis and provides measurement
results as an evaluation unit and control computer. The PGC 9300 is always oper-
ated together with the GC 9300.
3.1 Type designation
The various versions of the PGC 9300 differ depending on the application. The
designation PGC 9300 is used as a collective term in this manual. If differentiation
must be made between the variants, they are listed separately.
PGC 9301
This type is designed for use in "normal" natural gas. It operates with 2 column
modules (A and B) and can determine the gas components nitrogen (N
