3 Gas chromatograph PGC 9300
3.7 Separating columns
As already mentioned, two or three separating columns are operated in parallel in
the measuring element. The three column types in use are:
Channel A
44
Type: Haye Sep A
Channel B
Type: CP-Sil 5 CB
Channel C
Type: Molecular sieve
The process sequence shown in Figure 7: Gas (distribution principle diagram) ap-
plies for all channels.
3.8 Area of applicability
The PGC 9300 is normally operated in an Ex d housing in Ex Zone 1.
Safety classification:
II 2G Ex db e IIB+H
3.9 Data acquisition and evaluation
The essential points of data recording and evaluation are outlined in the separate
manual PGC9300_AC_manual_en. Only a few points that are relevant for the gas
chromatograph are covered here.
3.9.1
The basic factory setting assures good separation of the individual gas compo-
nents when passing through the columns. The corresponding parameter set is
identified as a method. Part of these settings is displayed and checked via the an-
alytical computer. The basic physical parameters of the analysis process that influ-
ence directly the analysis result and are defined in the method are the following:
