The winners of The Queen's Award for Enterprise 2009 have been announced. The Queen's award is Britain's highest accolade for business success and among this year's winners are companies with links to the separation science industry, including Thermo Fisher Scientific and SMI-Labhut.

Since the shortage in the supply of acetonitrile (ACN) began in late 2008, HPLC users suffer under more and more purchasing problems and higher costs. With our Eluent Savings Handbook we give you a range of practical tips and suggestions to help you deal with the acetonitrile shortage. Act now: Our Eluent Savings Handbook offers specific solutions for saving solvent, which will not only reduce the amount of HPLC eluents you use, but also benefit the environment by reducing waste. Learn more about how to save eluent by slimming methods, by UHPLC, by substitution and more.

A cool way to separate biological compounds is being developed by Japanese researchers. A stationary phase made of ice and water has been used to separate estrogen, amino acid derivatives and poly(oxyethylene) oligomers. Yuiko Tasaki and Tetsuo Okada from the Department of Chemistry at the Tokyo Institute used this phase to achieve a much larger theoretical plate number [(N) = 1,500] than previous ice experiments [N = 250] which allowed these applications.1 This novel stationary phase could be used to provide better separation selectivity for polar groups than silica gel, Okada told LCGC Europe.
