It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
The Agentase Chemical Agent Detection (CAD) Kit, formerly known as the Fido C1 CAD Kit, is an enzyme-based chemical detection kit that contains six different sensors that are designed to detect specific chemical warfare agents (CWAs) and other toxic chemical contaminants at trace levels. The kit is provided in a small pouch and can detect the ...

The equipment required is a colorimeter, some cuvettes and a suitable color reagent. The process may be automated, e.g. by the use of an AutoAnalyzer or by flow injection analysis . Recently, colorimetric analyses developed for colorimeters have been adapted for use with plate readers to speed up analysis and reduce the waste stream.
It's a classic tale: You have last-minute guests coming over for dinner or a bake sale fundraiser you didn't find out about until the night before—and now you need to concoct some tasty treats ...

The study also noted that "mace, nutmeg and tea reacted with the modified Duquenois–Levine [test]".
