GC–MS Authentication Method Developed for World's Most Expensive Coffee Beans
September 19th 2013Analytical chemists from Indonesia have developed a metabolomics-based method to determine the authenticity of the world?s most expensive coffee, Asian palm civet coffee (Indonesian Kopi Luwak).1 Currently, there is no reliable, standard method for determining authenticity, making it an ideal target for fraud.
EAS Conference Preview of Chromatography Sessions and New Features
September 17th 2013The Eastern Analytical Symposium (EAS) will be held this year from November 18 to 20, 2013, in Somerset, New Jersey. EAS is the second largest conference and exposition for laboratory science in the United States dedicated to the needs of analytical chemists and those in the allied sciences.
Potential Link Between Fracking and Water Quality Decline
September 12th 2013Kevin A. Schug, professor at the University of Texas, Arlington (Texas, USA) and LCGC North America EAB member, has led a team to survey and assess the impact of natural gas extraction from shale, also known as "fracking", on nearby water sources. The results of the assessment were recently published in the journal Environmental Science & Technology.1
Accelerating Your SPE Sample Clean-up
September 12th 2013The Microlute SPE sample preparation system from Porvair Sciences provides a faster, trouble-free alternative to cartridges for high throughput sample clean-up. Handling samples as small as 150?l the Microlute? SPE sample preparation system helps you increase your assay sensitivity by providing pre-injection clean-up and concentration you can trust.
The LCGC Blog: From HPLC to LC-MS: Mobile-Phase Composition is the Main Consideration
September 9th 2013Researchers coupling high performance liquid chromatography to mass spectrometry face the challenge of segregating the ionized, typically nonvolatile analytes from a large amount of solvent, and the mobile phase is an important component in the process. LCGC Blog editor Kevin Schug discusses factors to consider when choosing a mobile phase for LC-MS.

Making Successful Connections with Capillary Tubing in LC–MS Applications
September 6th 2013Choosing proper tubing connections throughout the entire system, especially when capillary tubing is used, can dramatically improve the level of sensitivity and quality of data obtained with most LC–MS systems.
Simultaneous Extraction of Metabolites and Lipids
September 6th 2013A German/Chinese team led by Rainer Lehmann, of the University of Tuebingen (Tuebingen, Germany) and Guowang Xu, of the DICP (Dalian, China), has developed a method of simultaneously extracting metabolites and lipids using methyl tert-butyl ether (MTBE) from single small tissue samples for analysis by ultrahigh-pressure liquid chromatography–mass spectrometry (UHPLC?MS).
The LCGC Blog: An Excel Tutorial for Modelling Chromatographic Separations
September 5th 2013Chromatography can be approximated by a series of equilibrium events between the mobile phase and stationary phase. Here, LCGC Blog editor Kevin Schug discusses an exceptional spreadsheet macro written by an undergraduate researcher that helps users visualize the development of chromatographic separations.
Agilent Thought Leader Award to Support Web-Based Tools for Cancer and Drug-Safety Research
September 5th 2013Emmanuel Barillot, Director of Bioinformatics and Systems IT at the Institut Curie (Paris, France), has received an Agilent Thought Leader Award. Agilent will contribute financial support, products, and expertise to the work by Barillot to develop a database of cellular signalling pathways and a visualization tool to help the pharmaceutical industry develop more effective cancer treatments. The web-based tool will enable the identification of off-pathway effects of new drugs.
