Chemical profiling and differential analysis of whiskies using Q Exactive™ GC Orbitrap™ GC-MS/MS
About this webinar
Whisky is a premium product produced using long established methods. The complex processes employed result in a final product that has unique characteristics and has high commercial value. As such, it is essential that whisky producers are able to obtain an accurate and comprehensive chemical profile which is characteristic to their individual product. This information can then be used to identify adulterated or counterfeit products and enable action to be taken, with confidence, to protect the product and brand.
Gas chromatography-mass spectrometry (GC-MS) is routinely used for chemical profiling applications due to its chromatographic resolution, reproducibility, peak capacity, and convenient spectral libraries. GC provides excellent chromatographic separation capability to enable a comprehensive chemical signature of a sample to be obtained. The recent introduction of high resolution, accurate mass (HRAM) Orbitrap Technology coupled to Gas Chromatography (GC) brings a new level of performance and flexibility in GC-MS full scan acquisition. This technology in combination with sophisticated software tools, that enable fast data processing and statistical analysis, has the potential to provide a complete workflow solution.
In this webinar we will highlight a proof of concept study using the Q Exactive GC in the characterisation and profiling of extracts of whisky samples. The importance of parameters such as high resolving power, excellent mass accuracy, wide linear dynamic range and automated deconvolution of HRAM spectra for the analysis of chemical components present at high and low concentrations will be discussed. The long term objective is to use such characterization data to identify counterfeit products and for quality control to ensure the consistency of products.
Attendees will learn how to:
- Use high resolution and high mass accuracy to investigate the chemical profile of complex samples.
- Apply a complete untargeted workflow using a novel Thermo Scientific™ Orbitrap™ MS-based GC and statistical software to detect and identify chemical markers.
- Learn about the current technology and software tools available for chemical profiling to potentially detect food fraud.

Dominic is a Senior Applications Specialist Thermo Fisher Scientific, Runcorn, UK. Dominic is an experienced analytical chemist and mass spectrometrist with more than 17 years of experience using state-of-the-art analytical systems. Dominic has worked in both a regulatory and industrial environment gaining strong hands-on experience with GC-MS and LC-MS systems used to investigate a variety of chemicals in food, biological and environmental samples.
The majority of his experience comes from ten years working at the fomer Food & Environment Research Agency as an Analytical Chemist focussing on method development using LC-MS and GC-MS systems for Food contaminants. Dominic is currently working primarily with GC-HRMS technology to develop and implement analytical methodologies for the detection and quantification of trace chemicals.
In recent years adulteration has become an increasing problem globally in the food industry and for consumers. Determining if the product has been adulterated is important for many reasons. Is the product pure; does it contain any contaminants; has it been adulterated in any way for economic reasons?
Thermo Fisher Scientific has advanced instrumentation that can help in the area of food adulteration to determine the known and unknown contaminants of the food and beverage product. Their state of the art products help labs check for the adulteration of edible oils to fruit juices and many other products. Their instruments help government agencies and contract laboratories determine if a particular product has been adulterated.
