Journal Highlight: Thermal desorption gas chromatography with mass spectrometry study of outgassing from polymethacrylimide foam (Rohacell®)

Date: Oct 12, 2015

Author: separationsNOW

Thermal desorption GC/MS was used to study the offgassed compounds from polymethacrylimide foams that are used as light structural materials in outer-space devices.

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.

Citrus oil sesquiterpenes: Multi-GC method characterisation

Date: Aug 24, 2015

Author: Steve Down

The sesquiterpenes in essential oils of citrus plants have been characterised by a combination of HPLC and several GC techniques, including 2D GC, to provide broader coverage.

Journal Highlight: Analytic setup for multicomponent high-pressure phase equilibria via dual online gas chromatography

Date: Aug 17, 2015

Author: separationsNOW

A high-pressure analytic phase equilibria setup was developed to produce accurate phase composition data for supercritical systems that is well-suited to handle mixture constituents ranging from volatile gases to mid-length hydrocarbons.

Hidden human emission profiles: Exogenous compounds should be included

Date: Aug 3, 2015

Author: Steve Down

Humans can be located from a group of volatile compounds emitted on the breath and through the skin, including exogenous compounds from personal care products and foods, to help in the search for disaster victims, bodies and hidden criminals.

Reclaimed tyre volatiles: GC and GC/MS profiles

Date: Jul 21, 2015

Author: Steve Down

The identities and levels of volatile organic compounds produced during the continuous thermomechanical reclamation of tyre rubber, measured by headspace GC and GC/MS, show that oxidative degradation occurs during the process.
