Phthalates in soil: GC reveals industrial contamination

Date: Jan 26, 2015

Author: Steve Down

The levels of six phthalate esters in the soil near an electronics manufacturing facility in China have been measured by gas chromatography following gas purge microsyringe extraction.

Journal Highlight: A multidimensional gas chromatography method for the analysis of hydrogen sulfide in crude oil and crude oil headspace

Date: Jan 19, 2015

Author: separationsNOW

2D Heartcutting GC was used to analyse dissolved hydrogen sulfide in crude samples, the gaseous hydrogen sulfide measurements being compared to liquid hydrogen sulfide measurements for the same sample set.

Parallel lines for GC: Simultaneous parallel field ionisation and electron ionisation detectors

Date: Jan 6, 2015

Author: Steve Down

A gas chromatograph has been successfully connected to electron ionisation and field ionisation mass spectrometers in parallel, allowing the simultaneous analysis of structurally diverse compounds in one run.

Milky phthalates: GC/MS method for 19 phthalate esters

Date: Dec 22, 2014

Author: Steve Down

A total of 19 phthalate esters have been measured in milk and milk powder by GC/MS following a QuEChERS technique and could be extended to other foodstuffs.

Journal Highlight: Enantiomeric separation in comprehensive two-dimensional gas chromatography with accurate mass analysis

Date: Dec 15, 2014

Author: separationsNOW

Chiral comprehensive 2D-GC coupled to quadrupole–accurate mass TOFMS was evaluated for its capability to report the chiral composition of several monoterpenes, namely, α-pinene, β-pinene and limonene, in cardamom oil.

Pollutant screening in water: Nearly 2000 contaminants by GC-LC/MS on one instrument

Date: Dec 5, 2014

Author: Steve Down

A combined GC-LC/MS set up has been developed to screen water for 1880 different organic pollutants of all types, including emerging contaminants like components of personal care products, preservatives and fragrances.

Carotenoids in sea salt: Source indicators

Date: Nov 10, 2014

Author: Steve Down

A group of ten volatile organic compounds selected from the many found in commercial sea salt can be used to distinguish it from industrial salt, independent of the geographical location.

Breath for breast cancer: Volatile aldehydes for diagnosis

Date: Oct 27, 2014

Author: Steve Down

Four aldehydes found on the breath have the potential to distinguish breast cancer from benign breast tumours and tissue from healthy people, leading to the possibility of an early diagnostic test for this prevalent cancer.

Journal Highlight: The volatile organic compounds of introduced and native dung and carrion and their role in dung beetle foraging behaviour

Date: Oct 20, 2014

Author: separationsNOW

Volatile emissions from dung and carrion of native and introduced animals in New Zealand, analysed using SPME and GC/MS, have complex profiles which potentially mediate foraging decisions.
