Dr Matthew Edwards is a separation science product specialist at SepSolve Analytical Ltd. He studied analytical chemistry at the University of Waterloo (ON, Canada) with particular emphasis on multi-dimensional separations. Dr Edwards is now focused on developing and applying powerful separation and detection technologies to complex analytical challenges.
This study demonstrates the high performance of a flow-modulated GC×GC–TOF MS system, coupled with sample preparation by solid-phase micro-extraction (SPME), for the separation and identification of trace volatiles in three brands of whisky.
This study shows that GC×GC and time-of-flight mass spectrometry provides a high-performance solution for screening complex coffee extracts for key aroma compounds. It further explains how this enables companies in the drinks industry to ensure that their products meet all quality assurance criteria, and that the taste and aroma expected by consumers is consistently maintained.
This study shows the value of dynamic headspace sampling and thermal desorption–GC–TOF MS analysis to rapidly profile volatile compounds released from flavoured cookies, and avoid the problems typically encountered when using solvent-extraction methods.
