Millipore’s new solid phase extraction (SPE) cartridges featuring 3M Empore extraction disks membranes produce clean extracts and minimise particle fines to potentially extend LC-MS/MS column life and reduce instrument downtime. Anticipated availability of the Milli-SPE Cartridges is second quarter 2006.
In 2005 Millipore began marketing and supporting 96-well Multi-SPE Extraction Plates that also feature 3M Empore extraction disk membranes for higher throughput applications.
SPE is often the preferred method for isolating and concentrating analytes at low detection levels because it eliminates the interferences that contribute to signal suppression. SPE yields clean, concentrated analyte solutions that allow improved signal-to-noise ratios and lower limits of quantitation in LC-MS/MS analysis.
Milli-SPE Cartridges will be available in a selection of sorbents (C2, C8, and C18; Universal Resin; and Mixed Phase Cation resin) to meet a broad range of application needs.
