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