Abstract
A system comprises: first and second mass spectrometers; at least one liquid chromatograph configured to simultaneously supply a first stream of chromatographic eluate derived from a sample to the first mass spectrometer and a second stream of chromatographic eluate to the second mass spectrometer; and a computer or electronic controller electronically coupled to both of the first and second mass spectrometers and comprising computer-readable instructions operable to: input a mass spectrometric analysis of a chromatographic fraction of the sample obtained by the first mass spectrometer; determine whether an additional mass spectrometric analysis of the chromatographic fraction of the sample is required, based on the mass spectrometric analysis of the chromatographic fraction obtained by the first mass spectrometer; and, if the determination is affirmative, cause the second mass spectrometer to perform, after a time delay, the additional mass spectrometric analysis of the chromatographic fraction of the sample.
