EPH Fractionation SPE Cartridges now Available in a 2 g Format

Resprep EPH fractionation SPE cartridges from Restek offers method-specific performance for extractable petroleum hydrocarbon (EPH) analysis of soil and water samples. These high-performing SPE cartridges completely separate aliphatic and aromatic compounds into distinct fractions, and they are guaranteed to produce background levels under the strict reporting limits of MA and NJ EPH methods.

Restek’s standard 5 g format cartridges are now joined by 2 g format cartridges made from the same high-quality silica. While the 5 g cartridges are recommended when higher loading capacity is required, the new 2 g cartridges are ideal for automated systems or when time-saving and solvent reduction are desired. As always, a rigorous QC testing and moisture-resistant packaging ensures storage stability and consistent lot-to-lot performance.
