MASS SPECTROMETRY DATA ACQUISITION MODE FOR OBTAINING MORE RELIABLE PROTEIN QUANTITATION

摘要

Described herein are methods and systems which enable a unique platform for analyte quantitation. The methods and systems relate to determining the amount of interference in a precursor ion isolation window resulting from an impurity. Once the level of impurity is determined, several methods can be employed to reduce the amount of interference in a subsequent MS/MS spectrum. The methods and systems described herein enable increased quantitation accuracy while maintaining high levels of throughput.
