Model: GCMS-QP2020EI NX, Auto injector AOC-20i plus and FID

CAI-K Gas Chromatograph (GC)

GC is an analytical instrument which is mainly used to separate volatile organic compounds which consists of a flowing mobile phase, an injection port, a separating column containing the stationary phase and a detector. The separation of the components takes place in the column on the basis of the physico-chemical interaction of the components with the stationary and the mobile phase. The components eluted from the column are detected and quantified by the detector.


  • Analyzing flavour and fragrance compounds
  • Analysis of pesticide and pharmaceutical intermediates
  • To trace volatile impurities in solid and liquid matrices


Column: DB1 column (Length-30m, ID- 0.25mm, Film Thickness-0.25micrometre)
Carrier Gas: N2 (99.995%)
Detector: FID & ECD
Integrator Software: GC Solutions


  • 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.

Sample Requirement

1g (in fine powder form) / 2ml (in liquid form).
Note:Samples in aqueous medium are not allowed for this method of Instrumental analysis
