Effects of experimental conditions on the determination of the effective carbon number

摘要: The response of the flame ionization detector (FID) is proportional to carbon number hydrocarbon molecules; however, heteroatoms attached chain can decrease detector's response. Sternberg was first who determined effective increments (ECN inc), which show how different atoms contribute a molecule as whole. If extent contributions or functional groups FID known, one could calculate relative analytes not available pure, authentic standards. An accurate and reliable quantitative analysis requires an determination ofECN inc. effects parameters influencing theECN inc value have be examined. Stemberg geometry However, we assume that other experimental conditions indirectly also affect theECN contributions. In this study, temperature injector, column injection modes were investigated. We compared values obtained at concentrations measured them with hydrocarbons intermal
