Abstract:
A portable X-ray fluorescence analyzer comprising: a measurement head section; an X-ray source disposed in the measurement head section for irradiating X-rays onto a sample for analysis of the sample utilizing principles of X-ray fluorescence; an operating section; a power source disposed in the operating section for supplying a voltage to the X-ray source to irradiate X-rays; a control circuit for controlling the power source to supply a voltage to the X-ray source through a first X-ray switch disposed in the measurement head section and a second X-ray switch disposed in the operating section by ON/OFF control of the first and second X-ray switches; and a safety switch disposed in the measurement head section for interlocking the first and second X-ray switches so that the control circuit controls the power source to supply a voltage to the X-ray source to irradiate X-rays only when the safety switch and the first and second X-ray switches are switched to an ON state.
