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.

Breath test could diagnose colorectal cancer

Date: Dec 1, 2015

Author: Ryan De Vooght-Johnson

Colorectal cancer screening is part of public health programmes in many countries, but compliance is low and there remains a need for better screening tools. According to a new study, a simple breath test could help to diagnose the condition, which kills thousands every year.
