SPE-Express is the ONLY system that:
• Both extracts the sample and evaporates the n-Hexane, eliminating the transfer step
• Uses a uid sensor to verify that the sample vessel is empty improving accuracy
• Runs multiple samples simultaneously on up to 6 stations improving analyst efciency
Simply load the 3-station SPE-Express with standard one-liter sampling jars and walk
away. The system ushes itself clean, preps the extraction disk, then lters and extracts
the sample through sodium sulfate with n-Hexane. In the nal stage the SPE-Express
automatically transfers the extract to a pre-weighed aluminum pan where it is evaporated
to dryness. Remove the pan for nal weighing and the process is complete. User-friendly
PC software controls the functionality while recording data for downloading to LIMS.
Product Features and Benets:
• Each system has three stations
• System is controlled with a PC using a single USB cable
• Two systems can be joined and connected to one PC for a total of 6 stations;
Laptop is included
• Each station can begin processing a new sample while a previous sample is being
evaporated
• System comes with software containing one default method and offers the ability for
the operator to create customized methods
• SPE-Express software allows users to have varying levels of access
• Fully enclosed unit does not require a fume hood
• System utilizes wide mouth (53mm) amber jars designated by the EPA method
• 33, 70, and 89mm adaptors are available for other bottle types
• Available in 120V or 240V
SPE-Express performs the entire process through evaporation to dryness in
approximately 45-50 minutes depending on the content of your sample.
• Prep – 5 Minutes
• Filter Sample – 15 minutes
• Elution – 20 minutes
• Evaporation – 7 minutes
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 lter until the sample bottle is empty and all
free liquid is removed from the lter.
• Elutes the sample with n-Hexane and removes any sample residue from the sample bottle.
• Vacuum lters 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 rst
is being evaporated.
The SPE-Express comes with a laptop and previously loaded easy to understand software.
The software:
• Allows the analyst to track the progress of each sample
throughout the extraction and evaporation process.
• Comes preprogrammed with EPA Method 1664 but allows
the analyst to create customized methods as well.
• Allows the Administrator to assign varying permission
levels to other users.
• Records all data through the extraction and evaporation
process for downloading to LIMS.
