Abstract

A method of analyzing a sample, the method includes separating precursor ions from the sample into narrow mass range groups based on mass-to-charge ratio; fragmenting the ions from each group to create groups of fragment ions; and mass analyzing fragment ions from each group of fragment ions using a long transient time mass analyzer, wherein the separation and fragmentation are decoupled from the mass analyzing and the cycle time of the high transient mass analyzer is greater than about five times longer than the cycle time of a narrow mass range scan time, and wherein the separation and fragmentation has a high duty cycle and the mass analyzing has a high duty cycle.
