The importance of GC and GC-MS in perfume analysis

TrAC Trends in Analytical Chemistry, 2002
Abstract Gas chromatography (GC) and mass spectrometry (MS) are by far the most important analytical techniques in the perfume industry. Both perfume houses (the suppliers) and the home and personal-care companies (the clients) rely primarily on GC and GC-MS for unraveling the composition of perfumes (i.e.

Biomarker Analysis Using GC-MSD

Journal of Chromatographic Science, 1990
The determination of biomarker compounds present in a crude oil is performed on an HP 5970 GC-MSD, a bench-top gas chromatograph-mass spectrometer, to demonstrate the instrument's feasibility for biomarker analysis. The sterane and triterpane distributions obtained from the GC-MSD analysis are compared to those produced by a research grade GC-MS, VG ...

Metabolome analysis using GC-MS

2006
Global changes in gene transcription (the transcriptome), and protein amount/activity (the proteome) ultimately effect metabolism and the metabolite content (the metabolome) of cells, tissues, and organs of plants. In the past, studies of plant metabolism focussed on one or a few genes, proteins, and/or metabolites.

Shortening Analysis Time (Fast GC)

2014
This chapter deals with the use of fast gas chromatography (GC) using narrow-bore columns. The influence of column parameters in order to shorten the analysis time is discussed from a practical point of view. While reducing analysis time, influences on sample capacity are discussed.
