HOW TO TEST METHAMPHETAMINE
The following flow chart will show you which test kits to use in order to fully test methamphetamine. Using the separation kit (TLC) along with this series of spot kits will produce the most reliable results available without sending a sample to the lab.
“COLOR MATCHES SPECTRUM”
This means that your reaction matched the spectrum and you can move down and left to use the next spot test kit.
This means that there was no notable color change. THIS IS A POSITIVE THING. The substance you were trying to identify was not supposed to react, but other adulterants (cutting agents) would have shown up instead if they were present. No reaction means that those adulterants were not present and you can move down and left to the next spot kit.
“ANY OTHER COLOR”
This means that your reaction was IN SOME WAY DIFFERENT than the expected reaction on the spectrum. At this point, you know that you either have a completely different substance from what you were expecting or an adulterated one. Returning or discarding the sample is the best course of action at this point although it is possible to use additional tests in order to tentatively identify the substance.
