Marquis, Mecke, Mandelin?

I'd say either Marquis or Mandelin , but as to which one of those is most suitable depends upon what substitutes you're likely to encounter.

Mandelin can indicate the presence of PMA and ketamine, Marquis is very sensitive to methamphetamine and both react to a wide range of compounds. Mecke is a useful reagent, only it's not as versatile as the others.
 
Any idea what concentration and ratio of formaldehyde/sulfuric acid makes up Marquis reagent?
 
^If it's to be stored for any length of time, add a small amount of methanol to slow down polymerisation of the formalin (usually ~1mL/100mL reagent)
