Hi,
I have a query about interferences in ICP MS. I am looking to quantify levels of Cu and Zn in soils and sewage sludge. Does anyone know the method used to overcome polyatomic interferences e.g. Cu63 with respect to Ar4ONa23? Also, what would the internal standard method correction be that would be used for matrix suppression. Finally, I am aware that Fe56 may have interference from Ar40O16 and Cr from ArCl, is there a method to correct for this,

Many Thanks
