Chromatogram view: To view chromatograms of the last stream processed. Two
chromatograms are available (switch views by selecting the tab for the desired
chromatogram):
The C3-C6+ chromatogram tab which shows the heavier boiling point peaks
The N2-C2 chromatogram tab which show the lighter boiling point peaks
The Peak Setup tab displays a table with key characteristics or parameters for each displayed
component peak. Some of these parameters can be modified such as the Gate On, Gate Off, and
Minimum Peak Area [Slope (Run), Slope (Rise), and Front Height Ratio cannot be modified].
IMPORTANT NOTE: Modifications to parameters in the Peak Setup table are processed by the
Post Process function without the need to run a cycle (Click Post Process after changes to view
the effect of the changes). Modifications to the Pressure and time/duration parameters require the
run of a cycle (Click Run a Single Cycle to view the effect of the changes).

It is assumed that a PCCU32 connection with the analyzer is successfully established, and the analyzer
Operation screen is in view. It is also assumed that a number of analysis cycles have already been
completed. If analysis has not taken place, there is no data to produce the chromatogram (the view
area is empty). The Peak Find chromatogram view window displays a message to instruct you to run
an analysis cycle.
IMPORTANT NOTE: All Peak Find procedures require Expert view.
To use the Peak Find function:
1. Click View on the top PCCU32 menu, select Expert. Wait for the change to take effect and
return to the analyzer Operation screen.
2. Click Hold on the Operation screen. The Operation screen should indicate the analyzer is in
Hold mode.
