Methamphetamines – Method 9106
2009
NIOSH Docket Number 176
Proposed NIOSH 9106 for Methamphetamine and Illicit Drugs, Precursors, and Adulterants by Liquid-Liquid Extraction and Gas Chromatography-Mass Spectrometry (GC/MS) is a sampling and analytical method that will be included in the NIOSH Manual of Analytical Methods, 5th edition. Two other proposed methamphetamine wipe methods will also be included. NIOSH 9109 is a Solid Phase Extraction Gas Chromatography-Mass Spectrometry (GC/MS) method and NIOSH 9111 is a Liquid Chromatography-Mass Spectrometry (LC/MS) method. NIOSH Method 9106 produces cleaner chromatograms and has longer operating times between mass spectrometer cleanings than NIOSH 9109 or NIOSH 9111. NIOSH 9109 has a quicker sample preparation time to run a larger number of samples, but has more problems with interferences than NIOSH 9106. NIOSH 9111 is the quickest and least expensive of the three methods, but has only been evaluated for the measurement of methamphetamine and not other illicit drugs of interest.

Peer review
Title: NIOSH Method 9106: Methamphetamine and illicit drugs, precursors, and adulterants on wipes by liquid-liquid extraction
Subject: New or updated method in a collection of methods to sample and analyze workplace contaminants.
Purpose: To detect surface contamination in order to avoid dermal exposures to illicit drugs, precursors, and adulterants, and determine clean-up effectiveness. Clandestine drug laboratories often are found after a fire or explosion and therefore pose a threat of injury to first responders, people who live or work near the laboratory, remediation workers, and future occupants.
