New articles on fragrance profiling & Markes’ involvement in QUAFETY food-safety project

Two new articles on the analysis of essential oils and the safety
of fresh-cut fruit authored by Markes’ staff have recently appeared in LCGC
The first article, in the September 2015
issue of LCGC: The Column, describes the use of GC×GC with Markes’
BenchTOF technology for analysing the complex mixture of volatiles present in
The article shows how GC×GC, combined with highly sensitive mass
spectral identification with BenchTOF, enables the rapid and effective
screening of essential oils. It also demonstrates the use of Select-eV soft
electron ionisation to assist identification of sequiterpenes while avoiding a
reduction in sensitivity.

The second article appears in the October 2015
issue of LCGC: Current Trends in Mass Spectrometry, and reports on the
VOC profiling of cantaloupe melon, as part of a collaboration between Markes International and a team of researchers at Cardiff University. The research, led by Dr Carsten Müller and Dr Hilary Rogers, was undertaken as
part of the EU-funded QUAFETY project for improving the quality and safety of
The article shows how a method based on thermal desorption with
GC–TOF MS can elucidate how key volatiles vary with the size of the melon
pieces, and highlights how such analytical information will be of value in
efforts to improve food flavor, understand shelf life, and detect microbial
