Each time I generate an EIC it seems to use only centroid and on very low signal the EIC will show dropouts as the centroid on low intensity date is outside the exact mass. the data is collected on a qtof from intact protein - I am trying to generate EIC chromatograms on protein masses that are close in mass (about 25Da on a 35,000 Da protein)
Hello Thorr ,
You can specify which data format to use for chromatogram or spectral extraction in the Qual Method Editor under Spectra->Extraction Data Format. The shipping methods default to Centroid.
Hello Thorr ,
The extraction range is specified in the Advanced tab of the Extract Chromatograms dialog. The default extraction for accurate mass data is 20 ppm, but you can change this to specify an m/z range if desired.
