2 February / March 2018 Foreword
Welcome to a brand-new year at Chromatography Today and the first edition of 2018. Last year was a great year for Chromatography Today with our first buyers guide, a growing readership and an increase in submitted articles. To keep the articles and features fresh and topical for 2018 we will retain the two general themes throughout the year - Fundamental Aspects of Chromatography and Modern Chromatography Applications to provide you with both advances in the fundamental aspects, method development and new instrumentation in analytical separation science and modern cutting edge and practical applications of analytical separation. The focus areas within these two themes for this edition are ‘Comprehensive GC x GC - recent advances’ and ‘Natural Products and cannabinoids in medicine’ respectively.
The Comprehensive GCxGC – recent advances is a follow-on focus area from the last issue on Hyphenated Techniques and the recent very successful HTC-15 meeting in Cardiff. In the current issue, we present an industrial article focusing on the offline and online approaches that are being utilised by Dow in both research and development and in routine applications describing the offline GCxGC analysis of hydrocarbon streams and how a seven-parallel reactor setup was coupled to online GCxGC. Other submissions from GC Image and SepSolve focus on the software and tools available that streamline the process of achieving robust and reliable quantitation in an acceptable time frame, with LECO showing how GCxGC and high-resolution time-of-flight mass spectrometry can be utilised for the non-target characterisation of environmental compounds of interest.
The Cannabis plant has been used as a medicine in many cultures spanning several thousand years, yet the use of medical cannabis is still controversial and currently being hotly debated by politicians in the USA and other geographies globally. Cannabis and cannabinoids have been recommended by doctors as a treatment to reduce nausea and vomiting during chemotherapy, improve appetite in people with HIV/AIDS, and reduce chronic pain and muscle spasms. Medical cannabis can be administered using a variety of methods, including for example liquid tinctures, vaping or smoking dried buds and eating cannabis infused edibles. The recreational use of cannabis is illegal in many parts of the world; however, the medical use of cannabis is legal in a growing number of countries including Canada, Chile, Colombia, Germany, Greece, Israel, Italy, the Netherlands, Poland, Peru, and Uruguay.
The use of cannabis as a medicine has not yet been rigorously tested and it is widely felt that cannabis products should be subjected to the same safety and quality testing that any other food or drug on the market is subjected to. Testing labs have sprung up to help meet the quality, safety, and labelling requirements for legalised cannabis products in different jurisdictions. But with the legality and acceptance of cannabis use still murky in many territories, such labs have often operated without the benefit of validated analytical methods and the collaboration or guidance from established governmental agencies. The cannabis production and testing

industry has matured rapidly, and many competent, certified testing labs are now providing reliable quantitative data to producers and consumers. However, because most cannabis testing labs have developed their own proprietary methods, with little cross-validation among labs and jurisdictions, many experts believe that there is a need for standardised analytical methods.
The ‘Natural Products - cannabinoids in medicine’ focus area covers the practicalities of cannabinoid extraction by supercritical fluid extraction (SFE) and the need of standardised testing, quality control and carefully planned execution of manufacturing and processing extracts with a group of articles developed by speakers that presented at the 2017 Waters Symposium on Extraction and Analytical Testing and the story of a company that has implemented GC testing authored by Ellutia Ltd.
The next issue of Chromatography Today will be focusing on UHPLC – Fourteen years on and Sample Preparation – Clinical Diagnostics.
Each edition of Chromatography Today is packed with valuable information, however it is impossible to include everything that is submitted. The new revised Chromatography Today website (www.
chromatographytoday.com) is the repository where you will find the other submissions, the latest news from the world of separation science and access to all the historical articles. Perusing the trending news and article sections, it is surprising how much separation science plays a part in daily life without us ever appreciating it, or even realising it. There is a diverse range of areas highlighting just how important separation science is to society with a calendar of events and articles on food, biofuels, medicine, forensics, brewing and environmental clean-up. Please take a look and if you are not a current recipient of the Chromatography Today e-bulletin – please sign up today.
As always we welcome article submissions, topic ideas for inclusion in future issues and feedback from our readership. If you have any feedback on this edition of Chromatography Today, please contact us as we are always looking to improve the publication.
Trevor.
