A.3 Calibrator Cartridge
The concentrations of the internal standards are printed on
the Calibrator Cartridge. In addition to the calibrators and
solutions, the Calibrator Cartridge has a self-contained
waste bag for safe disposal of waste.
A.3.1 Traceability of Calibrators, Controls, and Standards
Chemistry analytes are traceable to the Standard Reference
Materials of the National Institute of Standards and
Technology (NIST). SO
