Mass Spectrometers are used to identify the chemical nature of organic compounds, by determining the mass to charge ratio of the molecules and of their fragments. These instruments can also be used for quantitative determination of the analytes, providing that appropriate standards are available for calibration.
Complex mixtures of organic compounds extracted from samples, have to be separated by Gas-Chromatography or Liquid-Chromatography before they can be analyzed with a Mass Spectrometer. GC/MS and LC/MS are hybrid instruments that combine these two functions.
The MS Laboratory is located in the Volcani Building.
