SPR 10% IDA 10 micron
SPR-IDA (Suspended Particulate Reagent – Iminodiacetate) is a sample preparation material for preconcentration of trace elements and reduction of high alkali metal (e.g. Na) sample matrix levels. The reagent consists of 10 micron diameter polymer beads that have been chemically derivatized with the iminodiacetate chelating agent. Small aliquots of the reagent can be added via a batch mode to a sample and separated with bound metals by gravity or centrifugation.
