Mecke color chart
Below is our most recent reagent color chart with instructions last updated October If you mix up the caps and put the wrong cap on the wrong reagent bottle, this may cross-contaminate the reagents and ruin them.
Validation procedures are described for 12 chemical spot tests including cobalt thiocyanate, Chat roulette similar, Duquenois-Levine, Mandelin, Marquis, nitric acid, para-dimethylaminobenzaldehyde, ferric chloride, Froehde, Mecke, Zwikker and Simon's nitroprusside. The validation procedures include specificity and limit of detection. Depending on the specificity of each color test, between 28 to 45 drugs or chemicals were tested in triplicate with each of the 12 chemical spot tests. For each chemical test, the best online sex chat colors resulting from positive reactions with known amounts of analytes were compared to two reference color charts. These chemical spot tests were found to be very sensitive with limits of detection typically 1 to 50 microg depending on the test and the analyte.
