A Procedure for the Sensory Analysis of Gas Chromatographic Effluents

A method ispresentedfor determining those volatile components of Jbods that have flavour significance. The method leads to quantitative flavour specifications called charm that can be displayed graphically. The procedure is baaed upon the relative odour detection thresholds of volatile compounds of known gas chromatographic retention indices.

Analysis of flavor volatiles of some Iranian rice cultivars by SPME-GC-MS

A combined gas chromatography–mass spectrometry (GC–MS) with headspace solid-phase microextraction (HS-SPME) method has been employed for the analysis of the flavor volatiles of some Iranian rice cultivars (Domsiah, Deylamani, Hashemi, Shirodi and Tarom). The samples were grown in different cities of Mazandaran province. The sampling procedure and chromatographic conditions were same for all sa...

A gas chromatographic procedure for detection of pathological organic aciduria.

A number of nonamino organic acids associated with inborn errors of metabolism can be detected by gas chromatography. The organic acids are extracted into ethyl acetate and diethyl ether, the extracts combined, and the solvents evaporated under nitrogen. The residue is taken up in carbon disulfide and an aliquot chromatographed on 5% neopentyl glycol adipate to separate short-chain fatty acids ...

Gamma Radiation Effects on Polydimethylsilane Stationary Phases for Use in Packed-Column Gas Chromatographic Analyses

Este trabalho estudou os efeitos da radiação gama como indutora da imobilização de fases estacionárias líquidas de polidimetilsilicones usadas para separações cromatográficas em colunas recheadas. Testes de extração em solventes mostram que doses moderadas de radiação gama (80-140 kGy) produzem imobilização (90%) da maioria dos polidimetilsilicones testados em suportes do tipo Chromosorb, apesa...

Enantioselective gas chromatography in flavor and fragrance analysis: strategies for the identification of known and unknown plant volatiles.

This review describes current analytical technology for the analysis of chiral constituents in essential oils and other natural volatiles, flavor and fragrance compounds, and covers some important results achieved by natural compound chemists, food chemists, perfumers, and molecular biologists. The technique of enantioselective gas chromatography (GC) is described and applied for assigning abso...
