Binning of low-res Agilent MSD-data?
Posted: October 7th, 2020, 3:16 am
Hi!
We are collecting GCxGC data using our Agilent MSD, but are having issues with importing the data and library searches.
For example, 1-methylnaphthalene has a base peak which is reported as 141.25 in Masshunter. When imported to GC Image, this is rounded to 141.5 which is further rounded to 142 when doing a library search. This results in false hits. In the settings, we're using data binning by integer values (but have tried all other settings)....Library searches from MH Qual. works fine.
