How to set the baseline in chemstation software?

Do you know how to set the baseline for the chemstation software? I would like to integrate the peaks like below, but....

the autointegration actually integrate with weird baseline. Do you know how to modify this baseline?

  • Open the GC Parameters in the Method & Run Control view.  In the Signals section, I believe there is an option to Zero the signal at the start of the run.

    I'd also recommend going into the TCD B settings and switching the Negative Polarity setting to the opposite of what it currently is.  That will invert the signal so the peaks are positive rather than negative.
