Very short columns filled with 1.9 µm particles were evaluated for the ultra-fast analysis of pharmaceutical formulations. Local anæsthetic, mydriatic and anti-hypertensive agents were chosen as analytes and a method was developed and validated for each of these substances, according to ICH guidelines. Excellent quantitative performance was obtained using an optimized chromatographic system that reduces the importance of extra-column effects and cuts the analysis time to less than 15 s.

Pittcon (Pittsburgh, Pennsylvania) announced that twelve sessions at Pittcon 2009 at McCormick Place South in Chicage, March 8-13, will be coprogrammed with the ACS Division of Analytical Chemistry (ACS-DAC).

Microemulsion HPLC

Microemulsion liquid chromatography (MELC) is a recent development offering reduced sample preparation times for complex samples and generic separation conditions applicable to a wide range of solutes. This article introduces the concepts of MELC and discusses the possible benefits and future applications.

A research group from Yanbian University and the Key Laboratory of Organism Functional Factors of the Changbai Mountain (both Yanji City, Jilin Province, China) examined the effect of the vapor pressure of the extracting solvent on the enrichment factor in headspace liquid-phase microextraction.

Researchers from the Technical University of Denmark and (Lyngby, Denmark) and the Danish Meat Research Institute (Roskilde, Denmark) used a mixed-mode reversed phase?anion exchange cleanup method followed by LC-MS with electrospray ionization time-of-flight detection to analyze mycophenolic acid in dry-cured ham, fermented sausage, and liver pate.

Researchers Philip Marriott from the RMIT University (Melbourne, Australia), Warawut Tiyapongpattana, and Prapin Wilairat from the Mahidol University (Bangkok, Thailand) have developed a 2D GC with FID method for determining the composition of biofuels that extends to the C4-C24 esters. They reasoned that a 2D separation, based first on boiling point then on polarity, would provide better resolution of the components.

Researchers at Beijing Normal University and the Institute of Beijing Criminal Science and Technology (China) used ion pairing high performance liquid chromatography (HPLC) to analyze 12 black inks and six red inks from various manufacturers in a number of countries.

Agilent Technologies Inc. (Palo Alto, CA) announced it has created a specialized training program to address the current melamine crisis in China. The program will be available in early October and is part of Agilent University, a multifaceted education program for Agilent's customers in China.

ESA Biosciences, a Magellan Biosciences company (Chelmsford, Massachusetts), announced that it has received the 2008 Frost and Sullivan North American Technology Innovation Award in the field of integrated metabolomics systems.

New research led by David Valentine of University of California at Santa Barbara (Santa Barbara, CA), Chris Reddy of Woods Hole Oceanographic Institution (WHOI) (Woodshole, MA), George Wardlaw, a graduate student in the Marine Science program at UCSB, and three other co-authors from Swiss Federal Institute of Technology and WHOI details how microbes are dining on thousands of compounds that make up the oil seeping from the sea floor.

PerkinElmer Life and Analytical Sciences (Waltham, Massachusetts) announced its partnership with the Water Environment Federation's and the International Water Association's World Water Monitoring Day (WWMD), a month-long program that begins on September 18.

Thermo Fisher Scientific (San Jose, CA.) has announced that its Atlas Chromatography Data System now supports Microsoft Windows Vista operating system.

Chromatide (Runcorn, Cheshire, UK), which develops polymer technologies to improve pharmaceutical and chemical production, and Separation Product's Kromasil, a brand of Akzo Nobel (Amsterdam, The Netherlands), have set up a research collaboration to develop and market improved silica-based high performance liquid chromatography (HPLC) media.

Pittcon (Pittsburgh, Pennsylvania) announced that twelve sessions at Pittcon 2009 at McCormick Place South in Chicago, March 8-13, will be coprogrammed with the ACS Division of Analytical Chemistry (ACS-DAC).

The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method was published by Anastassiades and colleagues in 2003. Since then, this method for the extraction and clean-up of pesticide residues from agricultural products, and its many variations, have been gaining in popularity.
