Effects of truncating the MS/MS mass-to-charge ratio scan range with “turbo” ion trap scan rate. Both the number of uniquely identified peptides and the percentage of product ion loss was determined by either truncating from the low-end (A) or high-end (B) of the MS/MS 100–2 000 m/z scan range. The distribution of product ions produced is densely populated between 100 and 1300 m/z (C). Note the scarcity of product ions above 1 500 m/z, suggesting this mass-to-charge ratio region may not be necessary.
