SIM 
Selected Ion Monitoring: Selection of two or more fragments or 
isotope ions from a mass spectrum, which are specific for an 
analyte. This increase selectivity and allows to identify a 
compound further by the given intensity ratio between the selected 
ions. 
S/N 
Signal-to-Noise Ratio: Determination of the peak-to-peak noise of 
the baseline of a chromatogram and comparison with the signal 
height of an analyte.
