WebContamination is usually identified by excessive background in the mass spectra. It can come from the GC or from the MSD. The source of the contamination can sometimes be determined by identifying the contaminants. Some contaminants are much more likely to originate in the GC. Others are more likely to originate in the MSD. Web22 jun. 2024 · We have been having an issue with some contamination in our Agilent 1100 LC system coupled to an API 3000 MS.
