The LZI Methamphetamine Calibrators are human urine-based liquids, and ready to use. The Negative Calibrator is a processed drugfree human urine matrix containing buffers, stabilizers, and less than 0.1 % of sodium azide. The calibrators are prepared by spiking known concentrations of d-methamphetamine into the Negative Calibrator. Calibrators are made from NIST traceable standards. *Actual concentrations of these calibrators are within ±10 % of the target value as determined by GC/MS or LC/MS. Values are provided only as guidelines and laboratories should determine the ranges based on their own test system and tolerance (2)
