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

TL;DR: In both leaf tissues, defoliation induced an increase in GA 53 level, while GA 20 and GA 1 levels decreased, suggesting that the GA 53 → GA 44 , as well as GA 19 → GA 20 , conversions were slowed down.

Measurement and prediction of dead times and column diameter in capillary gas chromatography by using air, methane and some solvents
TL;DR: In this article, a method for the determination of the hold-up time of column diameter by using experimental measurement of retention times is suggested, and the effect of the uncertainty of the diameter of the column given by the manufacturer on the dead time calculation is investigated.

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.
