Streams JULY 2010
You can edit the following parameters for a
defined stream used in GC calculations.
These parameters are also used for post-
analysis calculations that use stream-
specific base pressure and temperature
values. Note that these parameters are not
applicable for every application.
Auto Cal
Auto Base
enable/disable the automatic calibration
and baseline run (first check box sets the
automatic calibration; second check box
sets the baseline run)
If the automatic baseline run is enabled,
the GC performs an additional calibra-
tion run (before the calibration runs to be
averaged) without the calibration gas.
This run evaluates peaks caused by the
GC valve action alone; any peak areas
found are subtracted from the subse-
quent analyses. To view or print the
baseline run results, see Step 4.

Cal Setting Description
For the automatic calibration to work,
at least one stream switch (valve
event Strm Sw) must be included in
the corresponding TEV
(see Section 5.3).
Disabling the Auto Base setting will
delete existing CDT baseline data for
the associated stream.
