GC/MS is an ideal tool for clan-lab Volume 22 assessments, because it can sepa- rate out multiple drugs in a single, complex sample. April 2018 Edition One of the most common sample preparation techniques for unknown powders is a solvent extraction. This technique involves adding the powder to an organic-based solvent. A syringe is then used to extract a very small portion of the organic-based liquid sample and inject it into the GC-MS for analysis. Many chemicals can be detected and analyzed in the vapor phase, includ- ing solvents used in the production of narcotics. Pyridine is a common solvent used in the production of fentanyl and is likely to be discovered in a clan-lab scenario. In-Field Sample Collection, Decon, and Chemical Identification A GC-MS can be placed into Vapor Confirmation Mode and exposed to pyridine. SUMMARY GC/MS has long played a critical role in tradition- al laboratory-based chemical analysis and is the gold-standard for forensic analysis. But chemical emergencies rarely occur in the safety of a laboratory as evidenced by the rise in street drugs and clan-labs. Chemical emergencies can happen anywhere, ex- tending the need for GC-MS equipment beyond the lab. (Learn More. Unknown powders. They can be almost anything!
