ABSTRACT:
In various aspects, the present teachings provide systems and methods for reducing chemical noise in a mass spectrometry instrument that use a neutral chemical reagent and one or more mass filters to reduce interfering chemical background ion signals that are generated by ionization sources of mass spectrometers. In various embodiments, the neutral chemical reagent belongs to the class of organic chemical species containing a disulfide functionality.
