For verification of interelement and background correction factors at the beginning 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 (CRM8061), and Solution AB, a combination of interferents (CRM8061) and analytes (CRM8064). Solution A is prepared by diluting CRM8061 20-fold. Solution AB is prepared by diluting CRM8061 20-fold and CRM8064 100-fold; for example, 5 mL of CRM8061 and 1.0 mL of CRM8064 into a 100 mL volumetric flask, brought to volume with a matrix blank (see page 25). Once prepared, the solutions should be analyzed consecutively, starting with Solution A.
This Certified Reference Material (CRM) is produced and certified in accordance with ISO Guide 34:2009 and ISO/IEC 17025:2005. All information regarding the use of this CRM can be found on the certificate of analysis.
