Standard Test Method for Establishing Performance of Equipment and Assays for Field Detection of Fentanyl and Fentanyl-Related Compounds

1.1.1 This test method provides a procedure for characterizing the performance of field portable fentanyl detection equipment and assays when utilizing the test samples and statistical considerations described in Specification E3243.

1.1.2 This test method describes sample preparation and analysis protocols to use when characterizing the performance of various types of field fentanyl detection equipment or assays in a laboratory environment including gas chromatography/mass spectrometry (GC/MS), high pressure mass spectrometry (HPMS), ion mobility spectrometry (IMS), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, colorimetric assays, and immunoassays.

1.1.3 The intent of this test method is to analyze samples in a manner that is analogous to how they are analyzed in the field by Federal and State/Local/Tribal/Territorial (SLTT) law enforcement and first responders, but under much more controlled and reproducible conditions than those that would generally be achievable when conducting field testing.

1.2.1 When creating test sample mixtures, all concentrations are stated as weight/weight percent (mg/mg) for solid sample mixture test samples, and weight/volume (mg/mL) for solid and liquid test samples that are dissolved in a solvent. When creating diluted liquid test samples (for example, for detection of compounds solubilized in solvent prior to analysis), all concentrations are stated as volume/volume percent (for example, µL/mL).
