Pyrolysis-GC/MS fingerprinting of environmental samples

This paper describes four recent applications of analytical pyrolysis in environmental science and engineering. In all applications, samples were analyzed in order to provide information about the origin of organic matter or changes to an organic matrix. In the first application, pyrolysis-gas chromatography/mass spectrometry (GC/MS) and pyrolysis-GC/flame ionization detection (FID) were used t...

Comparison of GC-MS and GC×GC-MS in the analysis of human serum samples for biomarker discovery.

We compared the performance of gas chromatography time-of-flight mass spectrometry (GC-MS) and comprehensive two-dimensional gas chromatography mass spectrometry (GC×GC-MS) for metabolite biomarker discovery. Metabolite extracts from 109 human serum samples were analyzed on both platforms with a pooled serum sample analyzed after every 9 biological samples for the purpose of quality control (QC...

Comprehensive Analysis for Organo-bromine Compounds in Environmental Samples with GC/MS (EI/NCI)

Introduction. Brominated flame retardants (BFRs) are chemicals that are added to polymers that are used in plastics, rubber, textiles and other materials to prevent fires. Similarly to other organic pollutants, BFRs have persistence and bioaccumulation potential in organisms. Recently, BFRs have become of increasing concern in environmental samples, due to the increase of the concentration of B...

GC - MS analysis of Polygala

The present study presents the bioactive profile of Polygala arillata Buch.-Ham ex D.Don using GC-MS. The phytochemical constituents of leaf and stem ethanolic extracts of Polygala arillata were investigated using Fisons Gas-chromatography – Mass spectrometry. The mass spectra of the compounds in the leaf and stem extracts was matched with National Institute of standards and Technology (NIST) L...
