Austin, TX- February 19, 2007–  SACHEM announced today that they will exhibit at the international Pittcon conference next week in Chicago.  Dr. Barry Haymore, Director of New Technology Development, will be presenting on SACHEM’s new line of displacers for use in displacement chromatography.  Dr. Haymore’s presentation titled, How Pure is Pure?  Utilizing Displacement Chromatography to Identify Minor Impurity Components, demonstrates the power of SACHEM’s Isolis™displacers and displacement chromatography.

SACHEM’s Isolis™ displacers coupled with displacement chromatography can identify and quantify product impurities that other methods cannot detect. 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. Richard Goodin, VP of Technology at SACHEM.  “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.

In addition, SACHEM will offer “The Isolis System™ Challenge at the exhibition booth at Pittcon.  “The Isolis System™ Challenge is a game that helps us illustrates the principals of displacement chromatography in a fun way, explains Rosemary Hoffman, Biotechnology Market Manager. 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 The Purity Challenge will be awarded the new Apple Nano.
