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

Quantitative aspects of the programmed-temperature vaporization technique of sample introduction in parallel capillary column and microbore capillary column gas chromatography
F. Poy,L. Cobelli +1 more
TL;DR: In this article, two new application fields of the programmed-temperature vaporization technique are described, and the use of microbore capillary columns has been tested, and two different columns with the same injector but leading to two different detectors has been evaluated, mainly from the point of view of accuracy in determination.

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.
