Fast GC’s rapidity gives greater productivity

Date: Aug 15, 2017

Author: Ryan De Vooght-Johnson

GC-MS run times can now be much shorter than with traditional methods due to a number of recent developments. Scientists from Tel Aviv University applied a combination of open probe fast GC and mass spectrometry to obtain rapid results from a wide variety of different analytes.

Journal Highlight: Characterization of odorous contaminants in post-consumer plastic packaging waste using multidimensional gas chromatographic separation coupled with olfactometric resolution

Date: Aug 14, 2017

Author: separationsNOW

Post-consumer food packaging waste has been characterized by sensory analysis and 2D high resolution gas chromatography coupled with mass spectrometry and olfactometry to help produce odour-free recyclates.

Orbitrap defeats the athletes who cheat

Date: Aug 1, 2017

Author: Ryan De Vooght-Johnson

Detection of the increasing number of compounds used as doping agents by sport competitors represents a significant challenge. Scientists from the Brazilian Doping Control Laboratory at the Federal University of Rio de Janeiro and Thermo Fisher Scientific (Austin, Texas) have developed a new Orbitrap GC-MS method for detecting a variety of doping compounds.

Journal Highlight: Employing two-stage derivatisation and GC–MS to assay for cathine and related stimulant alkaloids across the Celastraceae

Date: Jul 17, 2017

Author: separationsNOW

A GC/MS analysis of cathine and related stimulants in 43 Celastraceae species has shown that cathine is unique to Catha edulis, and is not responsible for the stimulant properties reported in related Celastraceae species

Nerve agents detected when fluoridation selected

Date: Jul 14, 2017

Author: Ryan De Vooght-Johnson

The field identification of chemical warfare agents remains a challenge, particularly for less volatile compounds that are not easily detected by GC-MS systems. Japanese scientists from the National Research Institute of Police Science, INFICON’s Yokohama facility and Teikoku Sen-I Co. in Tokyo have devised a novel fluorinating device that converted VX nerve agent and others to more volatile fluorinated compounds to enable detection by GC-MS.

E-liquids’ hidden alcohol revealed by GC protocol

Date: Jul 1, 2017

Author: Ryan De Vooght-Johnson

E-cigarettes are increasingly popular, but doubts remain about their safety and the appropriate level of regulation. Scientists from the Virginia Commonwealth University in Richmond investigated the amount of ethanol in e-liquids by GC with headspace analysis, finding relatively high levels in a number of brands.

Answering Life's Questions with Spectroscopy

Date: Jun 28, 2017

Author: Jon Evans

Spectroscopy has been a common analytical technique in laboratories for many years. Recently, however, it has begun to emerge from the laboratory, both figuratively and literally, as more and more researchers discover that it is ideally placed to answer the questions they want to ask.

Plastic packaging pongs profiled by 2D GC

Date: Jun 15, 2017

Author: Ryan De Vooght-Johnson

Ideally, waste plastic packaging should be able to be recycled to make food packaging, but the presence of unpleasant odours means that this is rarely attempted. Scientists from two German institutions, the Friedrich-Alexander University of Erlangen-Nuremberg and the Fraunhofer Institute for Process Engineering and Packaging at Freising, used a combination of 1D GC, 2D GC, mass spectrometry and sensory analysis to detect compounds with strong odours in waste plastic packaging.

Journal Highlight: Validation of analytical method for α-dicarbonyl compounds using gas chromatography–nitrogen phosphorous detector and their levels in alcoholic beverages

Date: Jun 12, 2017

Author: separationsNOW

A GC-NPD method has been developed to measure α-dicarbonyl compounds including glyoxal, methylglyoxal and diacetyl in 101 alcoholic beverages then perform exposure assessments.

Heart-cutting GC stops citrus fakery

Date: Jun 1, 2017

Author: Ryan De Vooght-Johnson

Citrus fruits and their products, such as essential oils, are found in a wide range of foods and perfumery formulations, but can be adulterated with synthetic compounds or cheaper natural extracts. Scientists from South Korea and Pakistan used heart-cutting multi-dimensional gas chromatography and mass spectrometry to determine the enantiomeric excess of various citrus compounds, measurements of which should detect adulteration.
