It’s use in subsequent analyses is chosen by checkboxes in other tabs.Ĭomplete Analysis > Airbeam correction Airbeam Results: root:diagnostics:corr_fact Before pressing leaving the airbeam tab section, make sure that you have a good airbeam correction factor.Ĭomplete Analysis > PToF Corrections In the Corrections tab, press the PToF subtab. The airbeam correction factor should be near 1. A graph of the airbeam correction factor will appear. If you are analyzing data with v/w mode switching, select reference runs with both v and w mode runs in it.Ĭomplete Analysis > Airbeam correction Go to the PToF tab and make sure the Dva and DC markers checkboxes are unchecked. It is best to choose runs near a calibration period. In a graph (one often uses the diagnostics graph), right – clicking a marquee and choosing ‘Set Airbeam Reference’ from the options.

Entering a run number series (380-452) OR.Correction factor = (airbeam avg/airbeam).Ĭomplete Analysis > Airbeam correction On the Corrections tab, select the Airbeam (AB) tab For this example we will use the Auto-set option. We want to take an average of the airbeam at a specific region (airbeam reference value runs) and compute the ratio of this value to the airbeam values at all other runs. For the moment we consider only the MS airbeam. In the diagnostics graph, we see the PToF and MS airbeam. For each run the airbeam value (mass 28) changes, often by a relatively small amount. Īirbeam Correction Discussion The airbeam value is a measure of the overall amount of sample we measure. When the gold Do Corrections button is pressed, the actions as checked in each subtab will be performed.
