Each GCMS-PT single test panel includes four samples verified as being detectable by both field-grade and laboratory-grade GC-MS instruments. Each sample is uniquely numbered and contains approximately 0.5 g of solid material or 1 mL of liquid material. Specific targets vary by sample, but cover compound classes such as explosives precursors, white powders, illicit drug-related chemicals, pesticides and related chemicals, TICs & TIMs, chemical warfare-related compounds, poisons, and pharmaceuticals.
