SPE cartridges for extractable petroleum hydrocarbon now available in a 2 g format
Apr 18 2019
Restek’s Resprep EPH fractionation SPE cartridges offer 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 very low background levels. 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, Restek’s rigorous QC testing and moisture-resistant packaging ensure storage stability and consistent lot-to-lot performance.
