ABSTRACT:
A hand-held XRF analyzer including an x-ray source for emitting x-rays through a window to a sample. A detector behind the window is responsive to x-rays irradiated by the sample. A controlled volume about the x-ray source and the detector is maintained in a vacuum or a predetermined purge condition for a predetermined amount of time for increasing the sensitivity of the analyzer. A processor is responsive to the detector for analyzing the spectrum of irradiated x-rays and responsive to a pressure sensor for detecting a pressure change inside the controlled volume. The processor is configured to detect if the vacuum or the predetermined purge condition has been compromised.
