Phenomenex Inc., a global leader in the manufacture of separation science consumables, introduces Strata-X-A to its line of solid phase extraction (SPE) products.  Strata-X-A polymeric, high-capacity sorbent delivers maximum retention of anionic compounds, rounding out Phenomenex's complete offering for anion/cation exchange separations.  The base polymer of the new Strata-X-A is pH-stable and resists deconditioning, providing more flexibility during method development and reducing the potential for errors.  

Strata-X-A retains acidic analytes in three different ways:  π-π and hydrophobic interactions coupled with a strong anion exchange mechanism.  The strong ionic bond allows an aggressive organic wash, leaving the eluent free of interference.  This sorbent is ideal for a wide variety of LC and GC applications that involve acid analytes including environmental and forensic toxicology. 

"This new product completes our Strata-X SPE, line which now offers products for just about any application," commented Erica Pike, brand manager for Phenomenex.  "As the use of SPE grows in a wide range of applications, we are pleased to have a strong offering featuring our novel polymeric base." 

Strata-X-A will be offered in 1, 3 and 6 mL tubes for traditional cleanup, 96-well plates for high-throughput extractions, and Giga^TM Tubes (12, 20, and 60 mL) for large-volume applications.   

Phenomenex is a global technology leader committed to developing novel separation, purification and analytical chemistry solutions for the life sciences and related industries.  Phenomenex's core technologies include products for liquid chromatography, gas chromatography, sample preparation, bulk purification chromatographic media, and chromatography accessories and equipment.  For more information on Phenomenex, visit www.phenomenex.com.
