CAI-K Gas Chromatograph-Mass Spectrometer (GC-MS)

GC-MS is a hybrid analytical instrument that couples the separation capabilities of GC with the detection properties of mass spectrometer (MS). The sample solution is injected into the GC inlet where it is vaporized and swept onto a chromatographic column by the carrier gas. The sample flows through the column and the compounds comprising the mixture of interest are separated by virtue of their relative interaction with the coating of the column and the carrier gas. The latter part of the column passes through a heated transfer line and ends at the entrance to ion source where compounds eluting from the column are converted to ions. The next component is a mass analyser, which separates the positively charged ions according to various mass related properties depending upon the analyser used. After the ions are separated they enter into detector and the output from which is amplified to boost the signal.


  • To screen chloro-phenols in water and soil, polycyclic aromatic hydrocarbons (PAH), dibenzofurans, pesticides, herbicides and phenols
  • Analysis of biologically important aromatic amines
  • Identification of volatile components

  • Only volatile and thermally stable compounds can be analysed.
  • Samples should be dissolved in volatile organic solvents, hexane, chloroform, methanol, ethanol, ethyl acetate etc. can be used. Solvents like THF, DMSO, and WATER are not acceptable.
  • If you are submitting extracted solid samples, please mention the preferred solvent to be used.
