New SPE Sorbent With Strong Anion Exchange Functionality Extends Strata™-X Line

Phenomenex Inc. 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™ Tubes (12, 20, and 60 mL) for large-volume applications.
