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

Marine Metabolomics: a Method for Nontargeted Measurement of Metabolites in Seawater by Gas Chromatography-Mass Spectrometry.
TL;DR: A gas chromatography MS (GC-MS) method that avoids sample altering during salt removal and that detects metabolites down to nanomolar concentrations from less than 1 ml of seawater is developed, which demonstrates that SeaMet advances marine metabolomics by enabling a nontargeted and quantitative analysis of marine metabolites, thus providing new insights into nutrient cycles in the oceans.

Anxiolytic effect and tissue distribution of inhaled Alpinia zerumbet essential oil in mice.
TL;DR: All the behavioral assessments indicated that inhalation of AZEO had a positive anxiolytic effect, and it is necessary to consider tissue distribution for investigating the effects of essential oil inhalation.

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.
