Question

Drugs produced at clandestine labs are often complex mixtures. Of the three separation methods of GC, LC, and capillary electrophoresis (CE), what would be the most reliable laboratory method to use for profiling the seized drugs to determine their methods of manufacture and origins? Which would be a suitable method for performing onsite analysis and what type of sample introduction method is necessary? How does the molecular weight of the drugs affect the choice of methods? Consider the example of methamphetamine versus methanones Drugs produced at clandestine labs are often complex mixtures.

Explanation / Answer

For Methamphetamine -

Weight test will determine the net weight of the material. Evidence submitted can range from residue on a surface to stains on fabric to pounds or tons of seized material. Analysts use analytical balances to weigh the material and record the results for the analysis report. The weight test will also determine if the quantity of material is sufficient for further testing.

For Methanones -
