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

Phytochrome inhibits the effectiveness of gibberellins to induce cell elongation in rice
TL;DR: The data indicate that phytochrome regulates the sensitivity of the tissue towards gibberellins, that gibBerellin synthesis is controlled in a negative-feedback loop dependent on gibb Berellin effectiveness, and that at least two hormone-triggered signal chains are linked to the cytoskeleton in rice.

Polarity of polyester stationary phases
TL;DR: In this article, the authors compared sets of polyester condensates in gas-liquid chromatography by determination of their polarity constants both from the Rohrschneider probes at low temperature and usign a set of aromatic probes at high temperature.

A method for the identification of branched-chain paraffins by calculation of their retention index values on the basis of molecular structure and physical properties☆
TL;DR: In this paper, the retention times of branched-chain paraffins were shown to depend on their physical properties, especially molecular volume, when non-polar phases were used for their separation.

Identification and distribution of chrysene, methylchrysenes and their isomers in crude oils and rock extracts
TL;DR: In this paper, the effect of maturity on the distribution patterns of methylchrysenes in Tertiary lacustrine shales from the Liaohe Basin (East China) was investigated.

Chapter 11 Natural Hydrocarbons in Sea Water Alain Saliot
TL;DR: In this paper, the distinction between volatile and non-volatile hydrocarbons is assumed by the differences in the analytical procedures used and the different chemical and biological roles of the two different types of compounds in the marine environment.

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.
