SPR

Small Particle Reagent (SPR) is a well-known and utilized technique to develop latent prints on difficult surfaces such as wet surfaces like cold drink cans and automobiles with dew, oily surfaces, or textured surfaces.

Small Particle Reagent (SPR) is quick, inexpensive and effective on fresh fingerprints. SPR is composed of finely ground particles suspended in a detergent solution. These particles adhere to the fatty constituents of latent fingerprints to form a visible deposit. Latent prints developed using this method may be lifted using standard lifting mediums.
