可以单独和混合使用以下标液建立工作曲线，混合后的标液包含目标Target Analyte List (TAL)所有元素。仪器需每天或每次校准，校准标液需新鲜配制，用后丢弃。对于ICAL-2, ICAL-3, ICAL-4A，建议稀释100倍。对于ICAL-1，建议稀释10倍。Sb、Hg元素按需稀释。
May be used separately or mixed together for preparation of the analytical curve. When mixed, these solutions will yield a standard containing all of the elements in the Target Analyte List (TAL). Instruments must be calibrated daily, every 24 hours, or each time the instrument is set-up. Calibration standards must be prepared fresh for each analysis and discarded after use. A dilution of 100-fold is suggested for ICAL-2, ICAL-3 and ICAL-4A, and a dilution of 10-fold for ICAL-1. Antimony and mercury can be diluted as required.
For ISM 01.2, at least one of your calibration standards must be at the Contract Required Detection Limit (CRQL).
