Solid Phase Extraction

DigiSEP
Accessories and Reagents

The DigiSEP and Molecular Recognition Technology Gel cartridges concentrate and separate complex
sample matrixes. Several accessories are required to optimize results.

SPE Vacuum Manifold Set

SPE Vacuum Manifold Set is used to concentrate or separate up to 12 DigiSEP cartridge analytes
simultaneously. Each cartridge tip is placed into the luer stopcock hole located at the top of the SPE
vacuum manifold. Once the cartridge is conditioned, the vacuum pump is turned-on and each luer
lock valve is opened. Analytes are then filtered and the unwanted matrix is drained into the waste
station located in the base of the Manifold. Each cartridge is then rinsed to remove any undesired
component(s) that may have been absorbed on the sorbent; which are again drained into the Waste
Station.

The base of the DigiSEP manifold is split into two compartments: a Waste Station and Elution Station.
After rinsing the analytes, the top of the SPE vacuum manifold with cartridges is picked-up, rotated 180
degrees and placed back on the base of the manifold. The cartridges are now at the Elution Station
where a rack with 50 ml DigiTUBEs collects the analytes of interest from each cartridge. Samples
are then available for ICP/ICP MS analysis. Vacuum pump sold separately.

Vacuum Pump

The Vacuum Pump is recommended for use with the SPE Vacuum Manifold to provide a vacuum for
effective solid phase extractions. Each pump is equipped with a regulator and a moisture trap for
particle and moisture removal. Pumps are quiet with low vibration.

SPE Cartridge Adapter

SPE Cartridge Adapter connects two DigiSEP cartridges in a “top to bottom” format. The connected
cartridges are placed on top of the SPE Vacuum Manifold to filter or concentrate specific elements. For
example, using the SPE Cartridge Adapter to connect a DigiSEP Red and DigiSEP Green cartridge
to separate Cr(III) and Cr(VI) from an analyte (Application Note available upon request).
