Introducing the MSQ
_______________________________________________________________________The Data System
SIM Mode
This acquisition mode is used when only one or a few specific masses are to
be monitored during the acquisition. Since most of the acquisition time is
spent on these masses, the SIM technique is far more sensitive (typically
greater than a factor of ten) than full scan techniques. However, this
sensitivity does depend on the number of masses being monitored
simultaneously.
SIM is also a highly selective technique. Impurities present in the sample
that co-elute with the compound of interest will not affect the analysis as
long as they do not produce ions at the same m/z value being monitored.
SIM does not produce spectra that can be used for library searching routines.
