PerkinElmer and M. D. Anderson Cancer Center Collaborate
October 1st 2008PerkinElmer, Inc. (Waltham, Massachusetts) announced an arrangement with the University of Texas M.D. Anderson Cancer Center (Houston, Texas) that will bring the company's Array Comparative Genomic Hybridization technique to the cancer center.
Ultra-Fast Separations of Pharmaceutical Compounds with 10 mm Columns Packed with Sub-2 µm Particles
October 1st 2008Very 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.
Headspace Liquid-Phase Microextraction Solvent Vapor Pressure
October 1st 2008A 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.
Mixed-Mode Cleanup Technique for Drug in Meat Products
October 1st 2008Researchers 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 Develop 2D GC with FID Method for Determining the Make Up of Biodiesel Fuel
October 1st 2008Researchers 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.
Ion Pairing HPLC Used for Ink Analysis
October 1st 2008Researchers 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 Creates Specialized Training Program in China
October 1st 2008Agilent 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.
Study Reveals Microbes Dine on Thousands of Compounds in Oil
October 1st 2008New 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 Sponsors World Water Monitoring Day
October 1st 2008PerkinElmer 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.
NuGEN and Hamilton Create Automated Sample Preparation Instrument
October 1st 2008NuGEN (San Carlos, California) and the Hamilton Company (Reno, Nevada) have assembled an automated, total target preparation system for high-throughput processing of clinical samples for global gene expression analysis.
Chromatide Partners with Kromasil
September 30th 2008Chromatide (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.
Solid-Phase Method for Extraction of Pesticide Residues
September 30th 2008The 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.
