a. GC Run Time —Select this option if you want the ISQ system run to end when the
GC run is complete. This is the most common setting.
b. Probe Run Time —Select this option if you have a probe controller installed and you
want the ISQ system run to end when the probe run is complete.
c. Select Stop After —Select this option to set the number of minutes you want the ISQ
system to run. The end of the run can be between 0 and 1,000 minutes. This option
allows you to stop the acquisition when all the compounds of interest have eluted,
but the GC is still at an elevated temperature to keep the column clean. We
recommend you select this option it because saves burn time on the filament.
7. In the Scans pane, click a scan row to enter scan information.

a. The Time (min) column is used to set the time that the ISQ system begins to acquire
data after the GC starts. It is typical to have enough of a time delay to allow the
solvent to get through the column before starting an acquisition.
Note If some of the columns mentioned below are not shown in the Scans pane, you can
right-click on a heading and display them. You can also reorganize the columns by
clicking on the heading of a column and dragging it to the left or right.
