Analytical Reaction Gas Chromatography

Mehr zum Buch

Gas chromatography is a key technique for analyzing complex mixtures of volatile substances, yet it faces significant challenges. Identifying components in unknown mixtures is complex, especially without knowledge of homologous series. Overlapping peaks complicate qualitative and quantitative analysis, often requiring multiple columns. Additionally, unstable or nonvolatile compounds cannot be directly analyzed, and the sensitivity issues of certain detectors necessitate preliminary concentration steps. Employing chemical conversion can effectively address these limitations, enhancing the technique's applicability.
