Reduce sample interference, not system efficiency
Targeted MS, and in particular selected reaction monitoring (SRM), is the quantitative analysis method of choice on the Thermo Scientific TSQ Altis Triple Quadrupole Mass Spectrometer, enabling monitoring of up to 250 peptide-specific precursor pairs (precursors and product ions) per second while using 0.2 Dalton resolution for precursor ion selection. This dramatically reduces chemical interferences while maintaining high transmission efficiency.
