REMOVAL OF ION FROM SURVEY SCAN USING VARIABLE WINDOW BAND-PASS FILTERING TO IMPROVE INTRASCAN DYNAMIC RANGE

摘要

PROBLEM TO BE SOLVED: To provide the removal of ions from survey scans using variable window band-pass filtering to improve an intrascan dynamic range.SOLUTION: A full spectrum is received for a full scan of a mass range using a tandem mass spectrometer. A mass selection window of the full spectrum is selected and a set of tuning parameter values is selected. The tandem mass spectrometer is instructed to perform a scan of the mass selection window using the set of tuning parameter values. A spectrum is received for the scan from the tandem mass spectrometer. A band-pass filtered spectrum is created for the mass range, the spectrum including values from the spectrum for the mass selection window of the mass range. Systems and methods are also used to band-pass filter ions from two or more mass selection windows across the mass range and to remove ions from a mass selection window between two band-pass mass selection windows.SELECTED DRAWING: Figure 1
