Technology News - HPLC 2010

HPLC 2010, the 35th International Symposium on High Performance Liquid Phase Separations and Related Techniques, runs from June 19 to June 24, 2010 at the Hynes Convention Center & Sheraton Boston Hotel in Boston, MA.

Here’s a sneak peek at some of the new products that will be showcased at HPLC 2010.

HPLC Columns
VisionHT™
Booth 310

Available in 1.5, 3, 5 and 10 μm particle sizes in six different phase selectives spanning the full polarity spectrum
12,000psi pressure rating is compatible with all ultra high-pressure LC systems
Offer increased polar interactions to make neutral, non-polar compounds elute faster and retain polar compounds longer
Instead of frits, thin screens retain media in the column, minimizing dead volume

Liquid Chromatography Columns
Glass-Lined or PEK-Lined for Optimal Peak Shapes

The ProteCol™ liquid chromatography columns from SGE Analytical incorporate high-quality stationary phases and inert materials throughout the flow path, offering such benefits as optimized analyte recovery, superior peak shape and reproducibility, and less artifacts due to reduced carryover. The ProteCol™-P features a PEEK™ lining and the ProteCol™-G features a glass lining to prevent contact with metal. PEEK or polymer frits are used.

“Certain compounds will react with metal,” said Rob Freeman, Business Manager – Chromatography at SGE Analytical. “By eliminating metal contact you get a better peak shape, which leads to increased sensitivity”

In addition to offering better peak shapes, ProteCol columns exhibit stability when exposed to pH 1.0 buffers and demonstrate consistent reproducibility of thousands of injections (subject to sample purity and mobile phase conditions).

ProteCol LC columns are available in a range of models for analyzing molecules with varying pore sizes. The HQ203 and HQ303 are packed with stationary phases of 200Å and 300Å, respectively, for analyzing peptides, while the HQ1003 uses a 1000Å pore size packing material, for separating larger proteins. The HPH125 model has a specially modified stationary phase, making it suitable for use outside commonly recommended pH ranges.
