Phenomenex Strata-X-A SPE sorbent

Strata-X-A has been added to Phenomenex’s line of solid phase extraction (SPE) products. The high-capacity sorbent delivers maximum retention of anionic compounds, rounding out the company’s complete 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.

Strata-X-A retains acidic analytes in three different ways: <0x03C0>-<0x03C0> 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 suitable 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 clean-up, 96-well plates for high-throughput extractions and Giga Tubes (12, 20 and 60 mL) for large-volume applications.
