6.3.1 Editing the Component Table
The component table contains a list of the compounds to be analyzed, properties of the
calibration gas, the concentration of the various components of the calibration gas and
parameters used for integration.
Once the GC is setup it is unlikely that the user would have to add components to the list.
However, it may be necessary to change any of the time based parameter due to column
ageing and valve wear.
To edit the Component Table:
a) Collect a number of chromatograms from a gas of known composition and determine the
retention time for the peak maximum for the compound(s) of interest. It is recommended
that the average retention time from at least three runs be used to determine the
retention time.
b) Enter the names of each gas (if necessary), the retention time and the concentration of
the various components of the gas in the component table (Figure 6-5).

c) Inspect the various peaks in the chromatogram and determine the
Skimming Leading
Edge Start,
Skimming Leading Edge End
,
Skimming Trailing Edge Start
and
Skimming
Trailing Edge Stop
for each peak. This is used to determine the integration window for
each peak
The windows should be selected so that the integration includes the entire peak, but does
not include extraneous signals. A typical set of integration windows is shown in Figure
6-6.
