The Column - May 2007 - (Page 31)

May 2007 www.thecolumn.eu.com The Column Majors Shaping the Future Ronald E. Majors, Agilent Technologies, Wilmington, Delaware, USA. In this special feature Ron Majors examines recent trends and highlights in HPLC columns and consumables. The purpose of this report is to provide information about many of the new separation consumables and accessory products that have been introduced this year. The information is based upon manufacturers’ responses to a questionnaire mailed in December 2006. Because of space limitations and the fact that some manufacturers did not respond to the questionnaire, this report cannot be considered an exhaustive listing of all new products that are currently available. The products introduced have shown definite correlations to current research, development and application activity in the separation sciences. Columns and other products recommended by their manufacturers primarily for biomolecule separations or sample preparation are denoted in the product comments with the designation BIO. Some of these products can be used for general high performance liquid chromatography (HPLC) separations as well, but their main emphasis is for biological samples. I will cite specific information about bioapplications where appropriate. Because the sub-2 µm HPLC columns are still quite new and require special care in their use, I have classified them as speciality columns or in a new series if an entire family was introduced. In this feature, I will describe new introductions in the areas of reversed-phase, normal- and bonded-phase, ion-exchange and ion, size-exclusion (SEC), large- and preparative-scale and speciality chromatography columns. products, while in sample preparation, there were many products for solid-phase extraction (SPE) automation. Still, a large number of products were introduced for the separation, sample preparation and for LC–mass spectrometry (MS) measurement of proteins — still the hottest area in chromatographic research and applications. Many application specific columns for HPLC and GC were noted. A considerable number of new accessories in HPLC/ion chromatography areas were introduced. HPLC columns: Reversed-phase HPLC maintains its dominance and a Trends and Highlights General: This year, I observed that there was a continued trend in high-throughput techniques, especially in the HPLC and sample preparation areas. In HPLC, there was an increase in the number of short and long, sub-2 µm columns and ultrahigh-pressure 31 http://www.thecolumn.eu.com
