Technology breakthrough enables scientists to better analyze and prove product purity through greater sensitivity and precision in the identification of trace components.

(Austin, TX) - May 1, 2008 - SACHEM will be exhibiting at HPLC booth #511 in Baltimore May 12-15, 2008.  Dr. Barry Haymore, Director of New Technology Development, will be presenting a poster on SACHEM's displacers for use in displacement chromatography.

The poster, titled "dLC x eLC - Using Displacement Chromatography as the First Step in Multidimensional Chromatography Methods" demonstrates the power of SACHEM's Isolis™ displacers, as well as the power of displacement chromatography. Isolis™ displacers coupled with displacement chromatography removes 95% of main component interference without affinity resins or prior knowledge of component identity. The impurities are concentrated (10-400X enrichment) in discrete zones between main component bands. 

"These results are impressive and can be used in final lot analysis, characterization, process control and process optimization", remarks Dr. Haymore. "Proof of product purity is critical to biopharmaceutical companies and regulatory agencies. Now they have a technique that enables a significantly improved approach to this important challenge."

SACHEM will offer "The Isolis System™ Challenge" at the exhibition booth at HPLC. "The Isolis System™ Challenge is a game that helps us illustrates the principals of displacement chromatography in a fun way", explains Rosemary Hoffman, Director, Biotechnology Solutions Group. The object of the game is to isolate impurities where the contestant is the displacer and separates all impurities from the main components.   Top winners of challenge will be awarded the new Apple Nano iPod.
