assessments,
because it can sepa-
rate out multiple drugs in a single,
complex sample.

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.

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.
