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.

Journal Highlight: Application of gas chromatography–tandem mass spectrometry (GC/MS/MS) for the analysis of deuterium enrichment of water

Date: Jul 13, 2015

Author: separationsNOW

A sensitive method to determine deuterium enrichment in body water was developed to enable measurement of fat mass and fat-free mass in humans.

Bees know their onions: Floral scent attraction

Date: Jul 1, 2015

Author: Steve Down

The volatile compounds emitted by the nectar and flowers of onion plants have been correlated with the number of visits made by bees following a comprehensive GC/MS study.

Cannabinoids in children’s hair: External contamination dominates

Date: Jun 22, 2015

Author: Steve Down

The dangers of assessing cannabis compounds in children’s hair in child protection cases have been highlighted by researchers in Germany who found that external contamination of hair is rife and must be factored in.

Acrylamide in foods: GC with chemiluminescence detection

Date: Jun 1, 2015

Author: Steve Down

A simple GC method for measuring acrylamide in food could be used as a screening step before the more expensive GC/MS or LC/MS assays, says its Chinese developer.

Coal tar complexity: 2D GC and FTICR MS reveal thousands of components

Date: May 25, 2015

Author: Steve Down

Coal tar residues that collected on a Texan beach following an oil spill consist of thousands of individual compounds that were detected using a combination of 2D GC, 2D GC/MS and FTICR MS, say US researchers.
