Separation science consumables manufacturer Phenomenex has introduced Strata-X-A to its line of solid phase extraction products for LC and GC applications in environmental and forensic toxicology.
Strata-X-A polymeric, high-capacity sorbent is said to deliver 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 de-conditioning, providing more flexibility during method development and reducing potential for errors.
Strata-X-A retains acidic analytes in three different ways: 1/4-1/4 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 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 6mL tubes for a traditional clean-up, 96-well plates for high-throughput extractions, and Giga Tubes (12, 20 and 60mL) for large-volume applications.
