Resprep EPH Fractionation SPE Cartridge

Method-specific performance for extractable petroleum hydrocarbon (EPH) analysis of soil and water samples.
Complete separation of aliphatic and aromatic compounds into distinct fractions.
Guaranteed background level under the strict reporting limits of MA and NJ EPH methods.
Superior lot-to-lot reproducibility and storage stability ensured by rigorous QC testing and moisture-resistant packaging.
Choose 5 g cartridges for higher loading capacity; use 2 g cartridges for automated systems, time-saving, and solvent reduction.

Restek EPH cartridges have a sample concentration loading capacity of 5000 ppm per gram silica for 5 g cartridges (total 25000 ppm) and 4250 ppm per gram of silica for 2 g cartridges (total of 8500 ppm), per instructions. However, to ensure satisfactory fractionation and avoid breakthrough, actual elution volumes should be determined empirically prior to sample analysis. The procedure in Restek’s product instruction sheet is suitable for MA and NJ method QC levels; however, high-concentration samples may require dilution or modified solvent volumes.
