Strata EPH: Specialty Strata Phase

Strata specialty phases offer unique selectivity that is designed to meet specific industry needs.

An example of this is Strata EPH, a specially designed solid phase extraction sorbent, designed to give high recoveries for extractable aliphatic and aromatic hydrocarbons analyzed in the MASS EPH method.

EPH

Selectivity: specialized phase that retains analytes by various polar mechanisms.

Fractionation of aliphatic and aromatic extractable hydrocarbons from environmental samples

ABW

Selectivity: incorporates the mixed-mode selectivity of a strong cation and a weak anion exchanger for target analytes.

Fractionation of neutral compounds from acidic and basic analytes
