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

Olfactory Cues from Different Plant Species in Host Selection by Female Pea Moths
Gunda Thöming,Hans Ragnar Norli +1 more
TL;DR: In this article, the pea moth Cydia nigricana was found to be attracted to the sweet pea Lathyrus odoratus, but larval performance on that species was moderate.

Headspace Solid-Phase Microextraction Analysis of Volatile Components in Peanut Oil.
TL;DR: In this article, the authors used headspace solid phase microextraction (HS-SPME) combined with gas chromatography (GC) and GC-MS to examine the differences in the peanut oil aroma on the basis of variety, roasting temperatures, and pressing components.

A search for some ang1osperm hormones and their metabolites in caulerpa paspaloides (chlorophyta)
TL;DR: The best available methods were used to search for an‐giosperm hormones in the green alga Caulerpa paspa‐loides (Bory) Greville, and despite the presence of several peaks of gibberellin‐like activity in the bioassays, no gibbrellin or gibb Berellin metabolite was found in the thousands of full mass spectra examined.

Utilization of the solution-of-groups concept in gas—liquid chromatography
Michal Roth,Josef Novák +1 more
TL;DR: In this paper, the possibilities of utilizing the UNIFAC group model of activity coefficients for the prediction of gas-liquid chromatographic retention data are discussed and examples of the determination of the specific retention volumes of different types of solute compounds on both simple and mixed stationary phases, relative retentions, Kovats retention indices and differential sorption enthalpies are given.

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.
