GC-FID 분석을 이용한 휘발성 유기규소화합물 혼합가스의 검량특성

This study assessed the analysis method for measuring volatile organic silicon compounds (namely as siloxanes) by using gas chromatography with flame ionization detector. Calibration standard gas was made in a laboratory by using six volatile organic silicons as model gas. Two different types of working gas were prepared to evaluate quality control in GC-FID analysis. Less than 0.2 RSD% of repeatability of retention time was observed in the analysis of calibration standard gas. In the linearity test, the highest coefficient of determination (R2) was found to be 0.997 for L2 among volatile organic silicon compounds. This study demonstrated that quantification of volatile organic silicon compounds can be performed by using GC-FID analysis with direct injection mode, and the GC calibration can be covered by the gas-phase standard method.
