Patent ID: 7978820

Claim:
A combined X-ray diffraction, XRD, and X-ray fluorescence apparatus, XRF, comprising: an X-ray source which provides radiation simultaneously over a continuous range of wavelengths, the radiation including a plurality of characteristic lines; a beam conditioner system arranged to define an incident X-ray beam in the diffraction plane in an incident beam direction; a sample holder arranged to hold a sample in the incident X-ray beam, the sample holder defining a sample plane; an XRF port positioned for measuring X-rays off the sample with an X-ray detection system mounted on the port to do fluorescence analysis; an XRD port arranged at a fixed 2 θ angle to the incident beam direction for measuring diffracted X-rays, where 2 θ is in the range 0.1° to 20°; and a beam conditioner system placed in alignment with the XRD port to select diffracted X-rays with an angle of 2 θ to the incident beam direction.
