Detailed Analysis: Easy Whisky Characterization

January 13, 2023

How do you handle the analysis and characterization of a complex sample like whisky*? In a recent interview with eFood Lab International, Dr. Geraint (Taff) Morgan of the Applied Science & Technology Group at the Open University, UK, says a 1D quadrupole GC-MS is sufficient for routine analysis, but when he really wants to dig into the non-target analysis of a complex sample, he turns to GC-TOFMS and GCxGC-TOFMS, such as that employed by the LECO Pegasus® BT 4D.

December 2, 2022

If you make the same thing the same way every time, you would expect to get the same results. But anyone working in a quality control lab knows just how much variability there can be on the same line, especially when working with organic materials such as those used to make whiskey. Small changes in temperature or atmospheric humidity, or the quality of the initial mash or final barrels can change the aroma profiles of the final products, and the aroma profiles themselves can be the first indicator of a problem on the production line if they can be analyzed and characterized with enough speed and confidence.
