Abstract
The volatile is a substance which has boiling point up to 200°C and changes its state from solid or liquid to gas. The devices available for sampling are based on physical and chemical properties of molecules hence these are not complete. The gas chromatography is instrument used for volatile study but it requires only volatile matter to be entered into it. So the better sampling device is required to avoid nonvolatile matter. Thermal and kinetic desorption separate the large number of molecules and enhances the efficiency of instrument like GC-MS. A sampler using thermo-kinetic principle was manufactured. Study of sampler shows 25 percent increase in peaks when analysed with GC. The aim of current study is to improve the design of presampler and carry out the experimentation on each of the component of presampler. Also to reduce the time required for completing the one testing of volatile in GC.
