2.3 INJECTION CHAMBER 2.3.1 Sample Introduction
ОглавлениеThe sample to be analysed is never introduced into the chromatogram as is, whether it is a liquid or a solid, but rather in a highly diluted solution. We use either a microsyringe (or loop injector) or a device such as a headspace sampler for volatile compounds, which both concentrates the sample and introduces it into the chromatograph.
