摘要
PROBLEM TO BE SOLVED: To provide a quantitative analysis method for measuring average density, the whole quantity, etc. of the respective elements contained in an object to be measured nondestructively by using a comparatively simple continuous X-ray source without using a large-scale device such as a synchrotron radiation facility (high energy electron storage ring), and to provide a quantitative analyzer by element for employing such quantitative analysis method.SOLUTION: Absorption edge jump of respective contained elements in an X-ray absorption spectrum of an object to be measured is calculated by using: a carbon-based cold cathode electron source; a target which is constituted of a conductive light element with an atomic number smaller than that of titanium and an electron emitted from a cold cathode electron source is made incident on a plane of incidence thereof, and which emits X-rays forward in the incident direction; a continuous X-ray source equipped with a shielding member which shields X-rays other than the X-rays generated by the target; and an energy discrimination type detector. Surface density on an X-ray transmission path is simultaneously measured for the respective elements contained in the object to be measured based on a mass absorption edge jump coefficient by every element predetermined by a standard sample, etc. and the absorption edge jump of the respective contained elements.
