Hydrophilic interaction liquid chromatography (HILIC) is the preferred method for the separation of polar compounds. Tosoh Bioscience introduces a new, amino-type HILIC column with high stability.

The use of HPLC for determining amphetamines has not received much attention because of the poor response of UV spectrometric detectors to these compounds when present at low concentration levels. However, HPLC coupled with mass spectrometry can provide the sensitivity required for the analysis of analytes at low concentrations in biological samples. In comparison to GC–MS and LC-UV analyses, LC–MS–MS offers superior sensitivity, selectivity and robustness for a wide range of analytes without any need for derivatization. LC–MS–MS technology also makes possible the development of highly selective, sensitive and precise methods for the simultaneous analysis of amphetamines and their metabolic derivatives. In combination with LC–MS–MS, limits of quantitation (LOQ) of 0.54 ng/mL are achieved for MAMPH, HMMA, and MDMA and LOQ of 1.0 ng/mL are achieved for AMPH and MDA on Gemini C18 HPLC columns.

DiGiuseppe Champion Meeting Review Pittcon 2009 This year's president, Ed Ladner, reflects on the success of Pittcon 2009 and demonstrates how the struggling global economy didn't take the shine away from its 60th celebration. News Protecting the Florida Everglades, securing nitrogen supplies, developments in ice chromatography and a discovery involving cheese are in the news this month. Incognito Pittcon Pioneers... After returning from Pittcon this year a little deflated by the lack of inspiration on offer, Incognito calls for a return to the inventive spirit and urges all entrepreneurs to demonstrate their creativity.

Event News

Euroanalysis 2009, which is organized under the umbrella of the Division of Analytical Chemistry (DAC) of the European Association for Chemical and Molecular Sciences (EuCheMS), has become a premier event for scientists to discuss and hear presentations on a broad spectrum of analytical techniques from a diverse range of applications. Euroanalysis aims to bring together analytical chemists from various fields to stimulate communication and strengthen networks in analytical sciences.
