A reason to wash your vegetables

Date: Mar 21, 2016

Author: Ryan De Vooght-Johnson

As well as damaging the environment, pesticides can be harmful to the consumer when residues are left on crops. A recent study analysed concentrations of over 50 pesticides in a range of commonly eaten vegetables, several of which exceeded safe levels.

Journal Highlight: High-throughput microanalysis of large lignocellulosic sample sets by pyrolysis-gas chromatography/mass spectrometry

Date: Mar 14, 2016

Author: separationsNOW

A high-throughput pyrolysis-GC/MS system for lignocellulose that incorporates automated multivariate-based data-processing was demonstrated on 300 Arabidopsis mutants and 5 biological replicate trees.

Defining the ‘fresh’ in fresh fish

Date: Mar 10, 2016

Author: Ryan De Vooght-Johnson

Fish is best eaten fresh, which can be difficult, given its very short shelf life. To identify the optimum window for eating cod, a team of French researchers used gas chromatography to detect molecular indicators of freshness.

Journal Highlight: Impact of comprehensive two-dimensional gas chromatography with mass spectrometry on food analysis

Date: Feb 15, 2016

Author: separationsNOW

The use of comprehensive two-dimensional gas chromatography with mass spectrometry in the untargeted (general qualitative profiling and fingerprinting) and targeted analysis of food volatiles has been reviewed.

The characteristic aroma of different Chinese liquors

Date: Feb 12, 2016

Author: Ryan De Vooght-Johnson

Chinese liquor is big business. Renowned for their characteristic flavours, some bottles can sell for over US $3000. However, what makes each liquor unique is not fully understood. A new study applied taste tasting alongside GC-MS to identify the tasting notes and volatile compounds associated with three major types of liquor.

Fighting fungal infection: detecting signature compounds in breath

Date: Feb 1, 2016

Author: Ryan De Vooght-Johnson

Oral thrush is the most common infection of the mouth, caused by a group of yeasts called Candida. Proper diagnosis currently requires time-consuming tests. Now, German scientists have developed a simple and rapid breath test to diagnose the infection.

Journal Highlight: Pesticide determination in rose concrete and rose absolute using dispersive-solid phase extraction followed by gas chromatography-tandem mass spectrometry

Date: Jan 18, 2016

Author: separationsNOW

The first analytical method to quantify 57 pesticide residues in rose concrete and 56 pesticide residues in rose absolute uses multistep dispersive-solid phase extraction by GC/MS.

High-throughput plant biology

Date: Jan 13, 2016

Author: Ryan De Vooght-Johnson

Lignocellulose, or plant dry matter, can be used to produce biofuels, making it a hot topic for research. Scientists in Sweden demonstrate the use of pyrolysis coupled to GC-MS to analyse biomass samples, creating a rapid, simple and affordable technique for plant chemical analysis.

An unsolved mystery in forensic toxicology

Date: Jan 1, 2016

Author: Ryan De Vooght-Johnson

The identity of two compounds in heroin had been an unsolved forensic mystery for three decades. Researchers in a DEA laboratory have now characterised the compounds, and describe how they solved the mystery in Drug Testing and Analysis.

Journal Highlight: Identification and quantification of bisphenol A and bisphenol B in polyvinylchloride and polycarbonate medical devices by gas chromatography with mass spectrometry

Date: Dec 14, 2015

Author: separationsNOW

A published GC/MS method developed for the identification and quantification of 14 phthalates and five nonphthalates in PVC medical devices has been extended to include the endocrine disrupting bisphenol A and B.
