2 May / June 2016 Foreword


Welcome to the second edition of Chromatography Today of 2016. The themes for this edition are capillary chromatography (which covers both capillary GC and capillary HPLC amongst others) and food and beverage analysis.


Trevor Hopkins - Editor


The food and beverage theme in this issue features almost exclusively on the subtly different approaches to the analysis of sugars and the interest in monitoring sugar intake, all arising due to the increasing incidences of obesity and diabetes across the developed world. As noted in the article submission by Stephanie from Metrohm; ‘From December 2016, the European Union (EU) requires that nutritional values are indicated on all foodstuffs, with the exception of unprocessed products and products sold loose (regulation no. 1924/2006)’. So the already established practice, in many countries of world, of indicating the calorific value and nutrients including sugar and carbohydrates on food product labels, is now set to become mandatory in the EU and along with it a heightened interest in food and beverage analysis.


In January 2014 Mexico became one of the first countries in the world to impose a tax on sugary drinks. In line with the health concerns of Mexico, in imposing this tax, the chancellor of the exchequer in his recent UK Budget announced the introduction of a new sugar tax on the soft drinks industry in the UK. It is something that has been discussed for some time, but still came as a surprise. The move has been hailed by campaigners as a significant step in the fight against childhood obesity with the levy being aimed at high-sugar drinks, particularly fizzy drinks, which are popular among teenagers. The tax will be imposed on companies according to the volume of the sugar- sweetened drinks they produce or import.


The routine analysis of sugars and sugar alcohols, even when utilising the speed and separating power of HPLC, remains a challenge, due to the molecular similarity and the lack of chromophores for detection by UV. An alternative to refractive index and electron light scattering detection mass detectors are becoming increasingly popular with the ability to discern the sugar isomers and enhance quantitation by decreasing detection limits.


I am delighted to announce the addition of the following distinguished names to the Chromatography Today Editorial Review Board, all of whom I have known for many years whilst working with various silica suppliers;


Dr Richard Henry


Dick received his B.S. degree in Chemistry from Juniata College in 1963 and PhD in Analytical Chemistry from The Pennsylvania State University in 1966. After a prestigious career with companies such as DuPont and Spectra Physics, in 1985 he joined the Penn State


University chemistry faculty and also founded Keystone Scientific, Inc. where he developed HPLC columns and related separation technology.


Dick retired from both Penn State University and Keystone Scientific in 2002, and remains active as a consultant and teaches short courses on separation technology.


Dr Gerard Rozing


Gerard worked for Agilent in Germany for 33 years in various Research and Development functions, retiring in August 2012, he is now a consultant and was awarded the Uwe Neue Award in Separation Science issued at the HPLC2014 symposium and recently as one of the top 100 most well-known analytical scientists in 2013 and 2015.


Dr Andrew Alpert


Andy received a B.S. degree from Yale and a PhD from Purdue U., and was responsible for developing some of the first materials for HPLC of proteins. After his post-doctoral research, Andy started PolyLC in 1985 to develop HPLC materials and techniques for life science applications. His specialty is the development of new modes of chromatography and new materials with which to implement them and in 1990 Andy was instrumental in the development of Hydrophilic Interaction Chromatography (HILIC).


A more detailed biography for all three of my colleagues is available online at Chromatography Today.


With these additions, and more to come, I am sure you will continue to see articles of the highest calibre on a multitude of chromatography topics for years to come.


I hope you enjoy this edition of Chromatography Today and look forward to seeing you at some of the meetings I attend each year such as ASMS, HPLC 2016, Prep 2016, ISC 2016 and SFC 2016. Watch out for the next issue of Chromatography Today with features on Chiral Chromatography and SFC.
