Our standard 5 g Resprep EPH fractionation SPE cartridges are now available in a 2 g format made from the same high-quality silica. While the 5 g cartridges are recommended if higher loading capacity is required, the new 2 g cartridges are ideal for automated systems or when time savings and solvent reduction are desired. These high performing SPE cartridges completely separate aliphatic and aromatic compounds and are guaranteed to produce background levels that meet MA and NJ EPH method requirements.
