Journal Highlight: Application of the fast sensory method 'Rate-All-That-Apply' in chocolate quality control compared with DHS-GC-MS

Date: Aug 15, 2016

Author: separationsNOW

The sensory Rate-All-That-Apply (RATA) method for quality control in chocolate production was compared with dynamic headspace GC/MS, showing that they should be used as complementary methods.

Beauty and the beast: Simple test detects cosmetic genotoxin

Date: Aug 1, 2016

Author: Ryan De Vooght-Johnson

Amongst the plethora of beauty products lurks a supposedly genotoxic beast. Spurred on by the lack of suitable detection tests, researchers from the Malaysian Palm Oil Board, the National University of Malaysia and the University of Malaysia collaborated to plug the void.

A breath of fresh air: sampling of δ13C and δ2H methane isotopes becomes simultaneous and automated

Date: Jul 15, 2016

Author: Ryan De Vooght-Johnson

Humanity has massively overdrawn its methane budget so the international community has agreed to take drastic action. To aid the monitoring of our methane expenditure and to track the sources of our bad habits, scientists from Germany and New Zealand teamed up to devise the first fully automated system able to simultaneously sample two methane isotopes in small volumes of air.

Chasing FAME: Fatty Acid Methyl Esters detected in trace amounts

Date: Jul 1, 2016

Author: Ryan De Vooght-Johnson

Trace levels of biofuel Fatty Acid Methyl Esters (FAMEs) in fossil fuels create problems, necessitating their levels to be minimal. To aid conformity testing, researchers from Victoria, Australia, banded together to devise a two-dimensional gas chromatographic method for separating FAMEs from co-eluents, enabling their quantitation at levels not possible before.

Fish: farmed versus wild

Date: Jun 15, 2016

Author: Ryan De Vooght-Johnson

With the rise of aquaculture, fewer and fewer fish are now wild-caught. A new study investigates the molecular differences between fish caught from the open sea to those that are farmed, finding significant differences in both fatty acid and mercury content.

Journal Highlight: IOFI recommended practice for the use of predicted relative-response factors for the rapid quantification of volatile flavouring compounds by GC-FID

Date: Jun 13, 2016

Author: separationsNOW

This recommended practice enables the quantification of volatile compounds in flavourings by GC-FID, without having authentic compounds available, and also in many cases, it can avoid time-consuming calibration procedures.

The hydroperoxide challenge: overcoming a lack of standards

Date: Jun 1, 2016

Author: Ryan De Vooght-Johnson

Hydroperoxides, reactive chemicals responsible for allergic reactions, are notoriously difficult to quantify due to a lack of standards. A study published in Flavour and Fragrance Journal however describes a new approach which overcomes the lack of commercially available standards and could improve quality control for a wide range of products, from perfumes to laundry detergents.

Detecting impurities in drugs by Orbitrap MS

Date: May 16, 2016

Author: Ryan De Vooght-Johnson

The quality and safety of drugs hinges on identifying impurities during development. Industry scientists now describe a method to accurately detect impurities – a combination of gas chromatography and Orbitrap mass spectrometry – which could be a powerful tool for pharmaceutical development.
