Solid phase extraction (SPE) is an
increasingly useful sample preparation technique. SPE is more efficient than liquid/liquid extraction, is easy to perform, and can be automated. However, certain samples, particularly those containing high solids, can create problems due to slow flow and clogging of the cartridge.

The Infinity™ SPE Cartridge is a reversed phase SPE cartridge that was developed specifically to enable simplified and faster sample preparation for high TSS aqueous samples. This results in
increased lab throughput and reduces overall cost of the analysis. It allows samples to be prepared by SPE which previously required liquid/liquid extraction or time consuming pre-filtration.
