Abstract
A new method has been developed for the estimation of an antistatic agent Glycerol Mono Stearate (GMS) in Polypropylene (PP) over Gas Chromatography coupled with Flame ionization detector (GC-FID). In the present work, selection of suitable sample specimen, sample weight, solvent mixture, extraction time, and temperature have been identified for the extraction of GMS in the PP resin. In-house Polypropylene pellet has been used for study and the GMS extorted into n-hexane-Ethyl acetate and quantified using GC-FID over 100% Dimethylpolysiloxane column. The method limit of detection is 1 mg/L and the limit of quantification is 5-750 mg/kg in PP resin with a correlation coefficient greater than 0.999. This method is accurate and has not found any interference with other co additives used in the propylene.
