Phenomenex Inc. introduced 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 offering for anion/cation exchange separations. The base polymer of the Strata-X-A is pH-stable and resists deconditioning, providing more flexibility during method development and reducing the potential for errors, according to the company.
Strata-X-A retains acidic analytes in three different ways: ¼-¼ 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 suited for a wide variety of LC and GC applications that involve acid analytes including environmental and forensic toxicology.
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.
