2 February / March 2020 Foreword
Welcome to a brand-new year and decade at Chromatography Today and the first edition of 2020. Last year was another great year for Chromatography Today with our Buyers’ Guide - now an annual feature, a growing readership and an increase in unsolicited article submission.
To keep the articles and features fresh and topical for 2020 we will retain the two general topics format throughout the year. The Fundamental Aspects of Chromatography and Modern Chromatography Applications are designed to provide you with both advances in the fundamental aspects, method development and new instrumentation in analytical separation science along with modern cutting edge and practical applications of analytical separation. The focus areas within these two themes for this edition are ‘Sample Preparation’ and ‘The cannabis explosion - THC & CBD Analysis’ respectively. These two themes will be separated by the Chromatography Today Knowledgebase which covers the use of mobile phase pH as a method development tool in liquid chromatography.
In the current issue for the Sample Preparation focus area, we present an article by Agilent explain the development and validation of a sample preparation method employing a novel synthetic SLE sorbent (96-well plate format) for the quantitative determination of an antiepileptic drug and metabolite in tissue samples. This article is followed by an article by Professor Giorgia Purcaro et. al. from the University of Liege which discusses the significantly improved kinetics of extraction when using vacuum assisted headspace solid-phase microextraction as a powerful tool for olive oil analysis.
This issue also has two off-topic articles which have been submitted by the authors - the first by Mattias Malm and Johan Kjellström of Ferring Pharmaceuticals, Denmark discusses the elimination of the sample solvent effect when analysing water based solutions of basic peptides by HILIC by using a column switching approach to enable the use of large injection volumes of aqueous samples. The second off-topic article is by Serkan Acar et. al. from Arven Pharmaceuticals, Turkey who provided a guide to the method development and validation of an improved method for dry powder inhalers.
The ‘The cannabis explosion - THC & CBD Analysis’ focus area covers the challenges of the analysis and isolation of cannabinoids in a rapidly changing arena. Interest in the therapeutic properties of compounds from cannabis such as cannabinoids has exploded in recent years. This has led to a significant increase in the number of products being released as nutraceuticals into a market which has fragmented
regulations at best. With no defined testing guidelines agreed for potency or impurities and

varying permitted levels of tetrahydrocannabinol (THC) globally it is important to have reproducible methods of analysis and procedures for THC removal. Articles from Shimadzu and ES Industries cover the analysis of cannabis in a compliant environment and the Supercritical Fluid Chromatography (SFC) Isolation and Purification of Cannabinoids using application specific stationary phases respectively.
The next issue of Chromatography Today will be focusing on Advances in Chiral Separations and Agricultural Applications.
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 ebulletin - 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.
