A device and method for identifying the composition of a target sample. The
target sample may be a matrix such as a metal alloy, a soil sample, or a
work of art. The device includes an x-ray fluorescence detector that
produces an x-ray signal output in response to the target sample. The
device also includes an optical spectroscope that produces an optical
signal output in response to the target sample. Further, a processor is
included that analyzes and combines the x-ray signal output and the
optical signal output to determine the composition of the test material.
In one embodiment, the optical spectroscope is a laser induced photon
fluorescence detector.
