每次测试开始和结束验证干扰和背景校正因子，另外每20个样品必需进行检测。标液INT-A1，稀释20倍，为溶液A，标液INT-A1稀释20倍再加标液INT-B3稀释100倍后混合，为溶液AB。溶液A和溶液AB用于最常见的干扰检测。一旦两种溶液配制好，需连续分析，从溶液A开始。
CLP ISM 01.2 and ILM 05.2 & 05.3 Standards for ICP
For verification of inter-element 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 (INT-A1) and Solution AB, a combination of interferents (INT-A1) and analytes (INT-B3). Solution A is prepared by diluting INT-A1 20-fold. Solution AB is prepared by diluting INT-A1 20-fold and INT-B3 100-fold; for example, 5 mL of INT-A1 and 1 mL of INT-B3 into a 100 mL volumetric flask, brought to volume with a matrix blank. Once prepared, the solutions should be analyzed consecutively, starting with Solution A.
