The bioplastic boom: plant-based packaging

Date: Dec 14, 2015

Author: Ryan De Vooght-Johnson

Alongside growing demand for less processed food, bio-based packaging is rapidly gaining interest. Researchers from Spain now report a rapid technique to characterise natural packaging, applied here to oregano-containing plastics.

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.

Floral quality assurance: tracing the origin of the Damask rose

Date: Nov 1, 2015

Author: Ryan De Vooght-Johnson

The Damask rose originally hails from Syria, but is now grown across the world. Chirality was used to determine the origin and authenticity of its essential oils by measuring enantiomer and diastereomer content using multidimensional gas chromatography.

Forensic fire investigations – a new way to detect foul play

Date: Oct 12, 2015

Author: Ryan De Vooght-Johnson

Analysing the residues left after a fire can be important in identifying its cause, and in some cases to prosecute for arson. This study applied gas chromatography and mass spectrometry to identify acidified fuels – often found in ‘Molotov cocktails’ – in the remains of a fire.

Metabolism of methoxypiperamide, a new psychoactive substance

Date: Oct 1, 2015

Author: Ryan De Vooght-Johnson

Recently, drugs that have similar effects to controlled psychoactive substances, such as cocaine and cannabis, have begun to emerge. These ‘new psychoactive substances’ mimic well known psychoactive drugs and are designed to evade drug laws. Widely available on the Internet, these substances pose serious risks to public health.

Sniffing out active compounds in insect pheromones

Date: Sep 15, 2015

Author: Ryan De Vooght-Johnson

Plant bugs from the Miridae family are an agricultural nuisance worldwide. Now in order to help with a novel control method, a recent study aims to identify the active components of pheromones produced by female bugs using gas chromatography.

Journal Highlight: Quantification of odor active compounds from Boswellia sacra frankincense by stable isotope dilution assays (SIDA) in combination with TDU-GC-MS

Date: Sep 14, 2015

Author: separationsNOW

A highly efficient method was described for the rapid quantification of selected odorants from Boswellia sacra frankincense, using thermal desorption to drive them from the sticky substance.

Skeletal drug analysis by GC/MS: Metabolites help to uncover drug history

Date: Sep 1, 2015

Author: Steve Down

A novel GC/MS method for measuring drugs and their metabolites in decomposed bones, illustrated with dextromethorphan and dextrorphan, will help to ascertain drug taking patterns of deceased victims.
