Assurance® Multi-Element Standards for AA & ICP
Interference Check Standards

The Interference Check Standards are used to set or confirm that he correct background correction intervals have been set for sequential ICP spectrometers and that the proper inter-element correction factors are set for simultaneous ICP spectrometers.

For use in US EPA Method 200.7 (Revision 4.4) and SW-846, Method 6010 (Third Edition).

Standards may be diluted in the same matrix as specified, however, caution must be exercised in the choice of the source for your diluents. Diluting the matrix may cause some standards to precipitate. Also, an impure or unknown diluent turns your standard into an unknown. We recommend using only SPEX CertiPrep matrix blanks when diluting your standard.
