Using Mass Spectrometers
SIM Mass Lists for IC-MS

SIM (Selected Ion Monitoring) is the Mass Spectrometer method used for recording an MS chromatogram at a specific mass-to-charge ratio.

The tables below list the SIM masses for anions, cations, and amines in water. Refer to the appropriate table when entering SIM masses in aQa or MSQ PGM Files, or to identify found masses.
