Abstract
A portable hand held XRF analyzer and method wherein an X-ray source directs X-rays to a sample and a detector detects photons emitted by the sample. A controller subsystem controlling the X-ray source an I/O section and is responsive to the detector and I/O section. The controller subsystem is configured to present to the user, via the I/O section, a choice to invoke an aluminum alloy algorithm test. An aluminum alloy algorithm test is invoked if the operator chooses the aluminum alloy algorithm test. Then, the X-ray source is operated at a predetermined voltage level and predetermined current level and the detector output is analyzed to determine elements and their concentrations present in the sample. Preferably, if the analysis fails to detect one or more common aluminum alloy elements present in the sample and/or fails to specify a particular aluminum alloy, then the X-ray source is automatically operated at a higher voltage and lower current level to repeat the analysis step.
