|Marquis:The Marquis Test is a reagent field test conducted by placing a drop of reagent liquid onto a small sample of the material being tested. The chemicals in the reagent react differently with different chemicals, turning a variety of colors based on the what is in the material being tested.||Yellow|
|Mecke:As with the Marquis Test, The Mecke Test is a reagent field test conducted by placing a drop of liquid reagent onto a sample of the material in question. Mecke reagent is primarily used for the identification of heroin and other opiates.||Yellow|

Should the public have access to independent analysis of the products they consume?
The vast majority of analyses of over-the-counter, prescription, and recreational drugs are performed in secret with no independent oversite or review. No other historical record, free from politically-controlled agencies, is currently available in North America nor most other parts of the world.
DrugsData, a project of Erowid Center, needs the support of professionals, students, parents, individuals with means, and small foundations for a total yearly budget of around $120,000 USD. Erowid Center's general budget and the co-pays we require fund most of this cost.Donate now
Overall, I'm not able to identify the sample from the results of the GC/MS. After looking at it carefully, my best guess is perhaps a substituted amine, perhaps an amphetamine-type molecule.
Many of the larger fragments are consistent with N-ethyl-N-propyl-amphetamine (MW = 205). The fragments that are the most useful though are the ones at 162, 176, 192, and 205. But after some time considering the options, I'm unable to come up with a solution that satisfies the mass spectrum. I can't explain the signal indicated at 192 (its relative abundance is vanishingly small). It differs by 13 mass units from the molecular ion. Some of the lighter fragments are within a proton (1 AMU) of being derivable from putative N-ethyl-N-propyl-amphetamine parent, but the match isn't perfect. Could also get MW = 205 with N-methyl-N-isopropyl-amphetamine, but then there are more fragments that are off by 1-2 AMU.
58.1: This is the strongest signal. called the base peak. Could be -CH(CH3)-NH-CH3, a monomethylated amine. Or it could be -CH2-CH(CH3)-NH2, a nonmethylated amine with a longer side chain. This fragment could indicate either an amphetamine or methamphetamine-type chemical. It could also be -CH(CH3)-N=O.
91: could be benzene ring-CH2-
105: could be benzene ring-CH(CH3)- or benzene ring-CH2-CH2-
121: could be benzene ring-CH(CH3)-NH2 or benzene ring-CH2-CH2-NH2 (phenethylamine)
135: could be benzene ring-CH2-CH(CH3)-NH2 (amphetamine) or benzene ring-CH2-CH2-NH-CH3 (N-methyl-phenethylamine)
149 could be benzene ring-CH2-CH(CH3)-NH-CH3 (methamphetamine)
162: molecular ion loses propyl group(205 - 43 = 162) --> benzene ring-CH2-CH(CH3)-N-CH2-CH3
176: molecular ion loses ethyl group (205 - 29 = 176) --> benzene ring-CH2-CH(CH3)-N-CH2-CH2-CH3
205: molecular ion --> benzene ring-CH2-CH(CH3)-N(CH2CH3)(CH2-CH2-CH3)
