Interference Checks For verification of interelement and background correction factors at the begining and the end of each analysis run. In addition a verification must be done after every 20th sample. Two solutions are required for the most common interference check: Solution A, the interferents alone (INT-A1), and Solution AB, a combination of interferents (INT-A1) and analytes (INT-B3). Solution A is prepared by diluting INT-A1 10-fold. Solution AB, is prepared by diluting INT-A1 10-fold and INT-B3 100-fold; for example 10mL of INT-A1 and 1.0mL of INT-B3 into a 100mL volumetric flask, brought to volume with a matrix blank (see page 13). Once prepared, the solutions should be analyzed consecutively, starting with Solution A.

SPEX CertiPrep® also provides a solution of alternate interferents and alternate analytes. Alternate Interferents A (INT-A2) and Alternate Analytes B (INT-B2) may be prepared in combination with the INT-A1 and INT-B3 solutions mentioned on the previous page, or any combination involving the four solutions, depending on the analytes and interferents of interest to you.
