Sample Preparation - Sample preparation of cement using fused bead for ICP

 
in ur application XRF VS ICP for concrete metals u have given a sample preparation using fused bead and then dissolving in Dilute nitric acid, i wanted to know whether the sample dissolves completely in the dil nitric acid or do you get some insoluble for that and then u filter to inject in ICP ?

If the fusion is performed correctly then the fuseate should dissolve easily in dilute nitric acid to produce a solution free of insoluble residue. If insoluble residues are observed then this frequently indicates an improper flux:sample ratio, incomplete mixing of the flux and sample, inappropriate temperatures/holding times for the fusion, or that a different fusion method is needed.
