A novel technique for accurately measuring CO2 gas flow rates has been used to develop a directly coupled SIWSFC (supercritical fluid extractionkupercritical fluid chromatography) technique for quantitative analysis of additives in polymers. The apparatus measures the concentration of CO2 in air at
