The following question and answer were taken from LCGC Europe's "CE Currents" column (1). How should I approach method development? If possible request any details of sample stability, pKa, and solubility in different solvents and pH ranges. Information on solvents used in HPLC can also be useful.

Size exclusion chromatography (SEC) is a powerful tool for the characterization of molecules differing in size and molar mass. It is widely used and well known for the determination of molar mass distributions and molar mass averages. For membranes GPC/SEC is a useful characterization method as it can measure the membrane characteristic pore size distribution, average pore size and molecular cut-off significantly faster than other methods.

Transforming "standard" gradient HPLC systems into extremely fast gradient systems is readily achievable with proper application of chromatographic principles, particularly temperature control, combined with utilization of advanced HPLC columns. Bottom line: You don't have to buy a new LC to achieve ultra high quality and speed!

PerkinElmer, 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.

Chromatide (Runcorn, Cheshire, UK) and Separation Product's Kromasil, a brand of Azko Nobel (Amsterdam, The Netherlands) have set up a research collaboration to develop and market silica-based HPLC media.

The 9th Csaba Horvåth Medal Award Symposium, to be held on April 28-29, 2009 at the Hartford Convention Center (Hartford, Connecticut), announced they are accepting papers for oral and poster presentations.

Part II of this three-part series focuses on comparing operation and performance of the most well known mass spectrometers.

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 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.
