| titleOfInvention | Monochromatic focusing X-ray light source and the method that Lead in low quantity arsenic is analyzed using the light source |
| abstract | The present invention discloses a kind of monochromatic focusing X-ray light source and the method using light source analysis Lead in low quantity arsenic, light source includes ray emission mechanism, preceding light bar, focusing ring and rear light bar, preceding light bar is arranged corresponding to ray emission mechanism, focusing ring is arranged in front of preceding light bar, light bar is arranged in front of focusing ring afterwards, focusing ring inner surface on the inside of focusing ring uses drum organization, and preceding light bar focuses ring inner surface and the coaxial arrangement of rear light bar, and axle center and the central axes of ray emission mechanism coincide.The present invention images X using cydariform condenser and carries out monochromatic, convergence, to form high-intensitive monochromatic light, can detect to low content arsenic element.The X-ray of irradiating sample of the present invention absorbs limit 11.867keV just above the K of arsenic element, can efficiently excite the characteristic X-ray of arsenic element but not excitation lead element, it is entirely avoided the interference of lead element characteristic fluorescence. |
