Description

The Rigaku SmartLab is a multipurpose X-Ray diffractometer system equipped with a high-flux 9kW rotating Cu anode and a 2D-detector. The X-Y-Z table holds samples up to 20 kg in weight and allows mappings on samples with a dimension of up to 87 x 100 mm. The device can be used for powder diffraction and for µ-spot analysis on different types of rock sections. Samples: Rock powders, sections up to 20 kg and 87 x 100 mm; Spot size: 100 μm / 300 μm / 500 μm

Instruments

A XRD - X-Ray Diffractometer is an instrument that uses a crystal to diffract x-rays for the measurement of the intensities of the diffracted rays. [Summary provided by The Photonics Dictionary] (Source: Global Change Master Directory (GCMD). 2023. GCMD Keywords, Version 16.3 [...] )

Measurement method using diffraction of X-radiation to obtain the spatial arrangement of atoms in a crystalline sample. Note 1: Bragg reflection follows nl = 2 d sin q, where l is the X-Ray wavelength, d is the spacing between atomic planes, and q is the angle of diffraction. Note 2: Copper K-a radiation (l = 0.15406 nm, E = 8.04 keV) is typically used for routine XRD.

XRD - X-Ray Diffraction
X-Ray Diffraction Analysis
An x-ray powder diffractometer is primarily used for the identification of phases in powder form. An x-ray beam of known wavelength is focused on a powdered sample and x-ray diffraction peaks are measured using a germanium detector; the d-spacing of the observed diffraction peaks is calculated using Bragg's Law [n*lamda = 2dsin(theta)]. The Scintag Pad V automated powder diffractometer uses a Cu x-ray tube with variable filters, a four-sample changer, and a low-noise, high efficiency, liquid-nitrogen cooled germanium detector. The goniometer is automated and software packages are run from a PC running Windows NT 4. A number of Scintag software packages are available for routine powder diffraction data acquisition, background correction and peak identification. Unknowns can be matched to JCPDS cards in an on-line database. Other software is available for quantitative analysis of powder mixtures, unit cell refinement, Rietveld analysis, and GSAS structural analysis. Samples sho uld be prepared as powders with a grain size of 10 um (approximately), and typically about 100 milligrams of sample is required.
