Small particle reagent is a suspension of fine molybdenum disulphide particles in detergent solution.

It adheres to the fatty constituents of latent fingerprints to form a grey deposit and is a quick and simple process.

The dish application method is a reasonably sensitive process but is very much more effective on fresh fingerprints than older ones.
 
The spray application (see # 95333) is considerably less effective and should be considered only when no alternative is feasible.

The grey powder may be lifted to simplify photography.
