Abstract
Developments in stationary phase synthesis and capillary column technology have opened new perspectives in the analysis of high molecular weight compounds (≥600 Da) and thermolabile organic compounds by high-temperature high-resolution gas chromatography (HT-HRGC). Apolar and medium polarity gum phases can now be operated at temperatures up to 400–480°C, and are being used for the analysis of compounds including n-alkanes up to C 100, lipids, oligosaccharides, industrial resins, polyglycerols, cyclodextrins, and porphyrins.
