Abstract

Disclosed is an attachable spacer applied to the front base plate of a hand-held and self-contained XRF testing device that holds the face plate at a forwards tilt towards a test sample, and ensures that only the top rim of the face plate ever touches a test sample. The resulting triangular gap minimizes contact between the front plate window and the test surface, prevents the transfer of heat to the XRF testing device's circuitry, and locks in a fixed distance between the face plate of the XRF testing device and the sample being tested.
