Portable X-ray fluorescence analyzer |
摘要 |
A portable X-ray fluorescence analyzer has a measurement head section and an operating section. An X-ray source is disposed in the measurement head section for irradiating X-rays onto a sample for analysis of the sample utilizing principles of X-ray fluorescence. A power source is disposed in the operating section for supplying a voltage to the X-ray source to irradiate X-rays. A control circuit controls 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. A safety switch is 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.
