Automation of EPA Method 1664

Wet Chemistry: Solid Phase Extraction/Oil and Grease

SPE-Express is the only

system that both extracts

your sample and evaporates

the n-Hexane. And the only

one that utilizes a fluid

sensor to verify that the

sample vessel is empty.

It will reduce time and

labor in your lab, improve

accuracy plus minimize

analyst contact with

hazardous chemicals.

SPE-Express Specifications:

Footprint: 22.25"w x 26.105"d x 22.343"h

Clearance: 2" all sides

Weight: 118 lbs

Crated: 200 lbs

Electrical: Available in 120V or 240V

SPE-Express is the ONLY system that:• Both extracts the sample and evaporates the n-Hexane, eliminating the transfer step

• Uses a fluid sensor to verify that the sample vessel is empty improving accuracy

• Runs multiple samples simultaneously on up to 6 stations improving analysts efficiency

Simply load the 3-station SPE-Express with standard one-liter sampling jars and walk away. The system flushes itself clean, preps the extraction disk, then filters and extracts the sample through sodium sulfate with n-Hexane. In the final stage the SPE-Express automati-cally transfers the extract to a pre-weighed aluminum pan where it is evaporated to dryness. Remove the pan for final weighing and the process is complete. User-friendly PC software controls the functionality while recording data for downloading to LIMS.

Product Features and Benefits:

• 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

• 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 adapters 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

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.

• Elution – 20 minutes

• Evaporation – 7 minutes

The SPE-Express software is easy and intuitive to understand.

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.

Use the Smart Bottle Rack with the SPE-Express for maximum efficiency.

The Smart Bottle Rack uses special

sensors to monitor the levels of reagents

and waste in your containers and alerts you

when they require attention.

The Smart Bottle Rack makes sure you

never run out of reagents or overflow your

waste container.
