The SPE-Express automates Oil and Grease Extraction and Evaporation as outlined in EPA Method 1664:
Preps the System
•
Rinses all system components with n-Hexane.
•
Preps the extraction disk with Methanol then replaces the Methanol with DI water to avoid co-solvent elution.
Filters the Sample
•
Vacuums the aqueous sample through the filter until the sample bottle is empty and all free liquid is removed from
the filter.
•
Elutes the sample with n-Hexane and removes any sample residue from the sample bottle.
•
Vacuum filters the eluted sample through the extraction disk then transfers the eluted n-Hexane through the drying
cartridge into a glass chamber.
Evaporates the Eluted Sample
•
Transfers the sample to a heated, pre-weighed aluminum pan for evaporation to dryness.
•
Allows the analyst to begin processing a new sample on the same station while the first is being evaporated.
