Abstract
A portable x-ray fluorescence spectrometer apparatus comprising a housing; a high voltage energized x-ray source operably secured within the housing; and an unheated electron cathode, operably linked to the high voltage energized x-ray source, thereby eliminating the need for a cathodic electron power supply for spectrometric analysis. Another embodiment comprises a portable x-ray fluorescence spectrometer having a housing, an integrated x-ray tube, a high voltage power supply operably linked to the integrated x-ray tube, and a mechanism for controlling the x-ray emissions of the x-ray tube and power supply including an electron suppression grid operably positioned between a filament cathode and a target anode of the x-ray tube.
