Gunshot residue (GSR) is produced from the condensation of the vapour cloud which is generated from the primer and propellant when a bullet is fired from a gun. The condensing vapour from the primer will form particles which are typically spherical and range from potentially less than 0.5 μm up to significantly larger sizes and of a characteristic composition depending on the type of ammunition. These particles may land on the hands and body of the shooter or other persons present when the gun was fired. By collecting and identifying these particles it is possible to associate a person with a crime scene where a gun was used
