Quantitative mineralogical analysis of small samples of china clay using x ray diffractometry.
The quantitative mineralogical analysis of small samples (less than 20 mg) of china clay has been investigated using x ray diffractometry to determine kaolinite, mica, quartz, and feldspar. A method has been developed and applied to the quantitative analysis of airborne dust samples and of other small discrete samples. Determinations were made either on samples after collection on a membrane fi...
متن کاملParallel Beam Powder Diffractometry Using a Laboratory X-Ray Source
We report on the application of a new, non-dispersive double multilayer optical arrangement to prepare a parallel beam from a laboratory x-ray source for standardization of powder diffraction reference materials and the associated high accuracy diffractometer. The beam preparation optic uses a graded-spacing parabolic multilayer to gather radiation from a small focus x-ray source and a subseque...
متن کاملApplication of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues
ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
متن کاملAnalysis of urinary stone components by x-ray coherent scatter: characterizing composition beyond laboratory x-ray diffractometry.
Monoenergetic x-ray diffraction (XRD) analysis is an established standard for the assessment of urinary stone composition. The inherent low energy of x-rays used (8 keV), however, restricts penetration depth and imposes a requirement for small powdered samples. A technique capable of producing detailed information regarding component structural arrangements in calculi non-destructively would pr...
