The SPE-Express® 2 system is intended for the automated extraction of oil and grease material following US EPA Method 1664. The self-contained unit employs a Solid Phase Extraction (SPE) disk to capture and separate oil and grease components from sample media. Components are eluted from the SPE disk using n-hexane and collected in an aluminum pan. Following elution and collection, the remaining solvent mixture is then evaporated through gently applied heat source removing the n-hexane and capturing the oil and grease component residue.
