Abstract

A time-of-flight (TOF) mass spectrometer analyzes a sample producing a time series of data points representing amounts of detected ions per unit time. A spectrometer resolution, a spectrometer digitization time period, and a minimum number points per peak needed to maintain the information content of a peak are received. A peak width value is calculated for each point from the resolution and a time of each point. The calculated peak width value for each point is divided by the minimum number points per peak. A maximum time difference between points for each point is produced. A point is selected based on the digitization time period. Adjacent points of the selected point are found. If a difference between the adjacent points does not exceed a sum of a maximum time differences of the adjacent points, the selected point is deleted to compress the time series.
