The SPE 2 option enables the automation of the conventional solid phase extraction using the MultiPurposeSampler MPS. Using the SPE 2 option, you can enrich and purify analytes from a sample. All steps that form part of the solid phase extraction process can be put together individually, enabling you to adapt the process to your analytical requirements. The system is controlled using the MAESTRO software. Within the software itself, all sample preparation steps can be prepped ahead to save time.
Functional principle of the SPE 2 option
Commercially available standard cartridges are fitted with transport adapters. Depending on the step to be performed, the MPS either injects a sample or a solvent into the cartridge. The liquid that runs through can be directed into a waste canister or collected in a clean vial. The SPE steps can be incorporated at any point within the automated sample preparation process and can be combined with additional steps that enable more extensive automated sample preparation, such as steps for the evaporation of the eluate using the mVAP option, for example.
During automated sample preparation, samples can be enriched and purified in a reproducible way to save time. By using standard cartridges, you can easily adapt your manual method for use with the SPE option. Solvent wastes can be collected separately according to their chemical properties, before being disposed of in a cost-effective and environmentally friendly way. Thanks to the MAESTRO software, controlling the system as a whole is simple and intuitive.
The SPE 2 option can be used with vials of different sizes and with cartridges of 3 sizes and containing different adsorbents.
