Drug purity testing kits

To compare reagents, check the table below. A ➕ sign indicates confirmation of the expected substance; at least two are recommended. A ➖ sign indicates exclusion of specific admixtures. A blank field indicates no use.

• Cannabis (4-AP) – main test for THC / CBD, helps rule out synthetic cannabinoids
• Ehrlich – main test for all indoles, e.g. lysergamides and tryptamines but also 5-HTP and more, secondary test for cocaine
• Hofmann – main test for lysergamides and tryptamines, more precise but slower than Ehrlich
• Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life
• Liebermann – main test for most powders, secondary test for cocaine (detects levamisole)
• Marquis – main test for most powders, secondary test for ketamine, mephedrone and psychedelics
• Mecke – main test for most powders, secondary test for cocaine, ketamine and mephedrone
• Morris – main test for cathinones, cocaine and ketamine, can tell apart some novel dissociatives
• Robadope – main test for primary amines, e.g. MDA, amphetamine or PMA
• Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
• Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD

Reagents Mandelin and Scott have been discontinued and replaced by superior Morris reagent. 

• Fentanyl Test Strip to detect fentanyl, even mixed in another substance.
• Nitazene Test Strip to detect nitazenes, even mixed in another substance.
• Xylazine Test Strip to detect xylazine, even mixed in another substance.
  
  

Reagents for identification can indicate PRESENCE, but not QUANTITY. Mixtures can only be detected with reagents if the additive causes a darker color reaction than the expected substance. Test strips can detect PRESENCE in any sample. To detect all components and estimate their quantity, combine the test strips and identification reagents with a TLC purity test.
