The Marquis Test is the most widely used testing reagent kit.
The United States Department of Justice method for producing the reagent is the addition of 100 mL of concentrated (95–98%) sulfuric acid to 5 mL of 40% formaldehyde. Different compounds produce different color reactions. Methanol may be added to slow down the reaction process to allow better observation of the colour change. This is done by slowing down the polymerisation process.

Place a small sample (2-5mg) of the substance you want to analyze in the provided plastic tube. If preferred, the test can be performed on a white ceramic surface for clearer results (e.g. kitchen plate). Add a drop of Smplest Marquis to the sample and expect it to immediately change colors. Use our legend to interpret results. When finished, clean all material thoroughly with plenty of water. The entire protocol takes approximately 5 minutes. Store at cold temperature, preferably in the freezer for longer shelf life (up to 12 months).
