The chemistry section utilizes the latest forensic science standards and best practices for the analysis of seized drugs and other substances. The section handles approximately 6,200 requests a year, the majority of which include drugs and/or drug paraphernalia. The weight and identity of a suspected drug is critical for law enforcement to be able to proceed through the criminal justice system. The most commonly identified controlled substances include methamphetamine, fentanyl/fentanyl analogs, cocaine, benzodiazepines, and delta 9-tetrahydrocannabinol. In general, an analysis consists of a preliminary test and confirmation test. The confirmation of a controlled substance can be done using GC-MS, FT-IR, GC-IR, or a combination of the listed techniques.
