GSR testing has been available in different forms for about
30 years, but all tests to date had one common feature and that is the
investigating officer 'swabs' the hands of the suspect to collect GSR particles
and then sends the swabs to a laboratory for analysis by various methods.
The laboratory method commonly recognized as most
reliable and practical is interpretation via Scanning Electron Microscope
(SEM). However, it can take weeks even months, to obtain results from a
laboratory, so the benefit to an officer offered by GSR testing has been very
limited. In fact, many officers don't even bother applying the technique,
despite the fact that it is a reasonably reliable technology!
This GSR kit is different in as much as it is a
"binary" test. This means that it allows the investigating officer to
test the suspect two times for GSR residues, once directly at the scene, which
provides an immediate investigative or "presumptive" benefit, and
again in the laboratory, which provides the "evidentiary" data for
use in court later on.
Full instructions are supplied in every kit.
