Q Exactive GCxGC data

Post by leowang »

Hi All:

I'm processing GCxGC data obtained from a Q Exactive GC instrument and the MS binning options does not seem to be working. The accurate masses are displayed only with one decimal (e.g., 121.3). I have tried the 'Uniform Bin' with many bin sizes and the spectrum exhibited in the 'Spectrum' window is the same with all bin sizes.

I'm using the v2020r2 GCxGC-HRMS and processing the CDF file.

Thanks,

Leo

There is a separate display setting in MS View. To change that setting,

Right click on the m/z column header on the Spectral Peak Table > adjust the decimal places to be displayed

, as shown below:
