Spice 1 (JWH-018) Control, Level 2 (25 ng/mL)

The LZI SPICE I (JWH-018) Controls are human urine-based liquids, and ready to use. The constituent is a processed drug-free human urine matrix containing buffers, stabilizers, and less than 0.1 % of sodium azide. The controls are prepared by spiking known concentrations of JWH-018 N-(5-hydroxypentyl) metabolite into the drug-free matrix. Controls 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).
