TLDR
In this article, a simple relation exists between the retention index of a compound on a non-polar stationary phase and its boiling point, which is defined as the ratio of the boiling point of the compound to its retention index.Abstract:
For the characterization of organic substances in gas chromatography a number termed «retention index» is proposed. A simple relation exists between the retention index of a compound on a non-polar stationary phase and its boiling point.read more

Gas-liquid partition chromatography: the separation of volatile aliphatic amines and of the homologues of pyridine.
TL;DR: Analysis of the volatile amines present in Chenopodium vulvaria L. shows the presence of only ammonia and trimethylamine, compared with standard mixture ofmono-, di and tri-methylamines, which indicates a low concentration of ammonia in the plant.
