Porvair Sciences announced the availability of a new guide that they say is designed to make the selection of the Solid Phase Extraction (SPE) microplate for application both quick and easy. SPE is a method of sample preparation that concentrates and purifies analytes from a solution by means of absorption, followed by the elution of the analyte with a solvent appropriate for instrumental analysis, with techniques such as LC-MS. The selection guide adopts a flow chart to enable you to select an appropriate Porvair Sciences Microlute CP SPE microplate by sample matrix (aqueous or organic), analyte charge, solubility and polarity, and finally, sample retention mechanism.
