Abstract:
The effects of blending time and rotation speed on the homogeneity of powder blends were examined. The concentrations of the samples were measured with an energy-dispersive X-ray fluorescence analyser, and control measurements were made with a UV spectrophotometer. The paired sample t-test showed that, for a large majority of the samples for which measurements were made to determine the concentrations, there was no essential difference. It may be stated, in accordance with the fitted equation, that the rotation speed and the square of the blending time exert significant effects on the distribution of the active ingredient. The energy-dispersive X-ray fluorescence analyser can be applied well for direct determination of the homogeneity of certain powder blends.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
