ABSTRACT:
A total reflection X-ray fluorescence apparatus comprises a base material having an optically flat surface for totally reflecting X-rays radiated at a small glancing angle, a first detector such as an SSD for detecting fluorescent X-rays emerging from a specimen located near the optically flat surface of the base material and a second detector such as a scintillation counter for detecting an intensity of an X-rays coming from the base material.
