X-ray diffraction is a common technique that determine a sample's composition or crystalline structure. For larger crystals such as .X-ray diffraction (XRD) is a versatile, nondestructive analytical technique that’s sensitive to the atomic structure of matter. XRD enables phase identification, quantification, and many more .
When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy it previously gained by excitation is emitted as a photon of one of the wavelengths uniquely characteristic of the element. Analysis of the X-ray emission spectrum produces qualitative results about the elemental compositi.

Today, X-ray fluorescence (XRF) technology is is well known to provide accurate, nondestructive elemental analysis. Using XRF, researchers can achieve rapid material characterization and analysis to ensure product chemistry specifications are met—and our XRF instruments provide the fast and reliable results they need.A spectrum within a certain wavelength range can be recorded simultaneously by using a two-dimensional position-sensitive detector such as a microchannel photomultiplier plate or an X-ray sensitive CCD chip . X-ray diffraction units were widely used in academic research departments to do crystal analysis. The technology used for the separation (dispersion), identification and intensity measurement of a sample’s X-ray fluorescence spectrum gives rise to two main types of spectrometer: wavelength dispersive (WDXRF) and energy dispersive (EDXRF) systems. Find out more about these spectrometer types and the technologies behind them here:The following spectra comparison shows spectra from a sample excited with Pd- (displayed in blue) and Co- (displayed in turquoise) anode X-ray tubes. For the analysis of potassium in this sample, using the Co-excitation provides higher sensitivity than using a Pd-excitation due to the absorption edge of potassium being close to the Co energy.

X-rays form part of the electromagnetic spectrum, and are characterized by energies lying between gamma and ultra-violet radiation (Figure 1). Wavelengths are typically in the range 0.01 to 10 nm, which is equivalent to energies of 125 keV to 0.125 keV.The measured spectrum shows lines or peaks that are characteristic for the chemical elements in the sample. The WinFTM Software computes the thickness of the coating(s) and/or the analysis result. The video image of the sample is shown in the WinFTM window. The precise position of the measurement location and the measurement spot is possible .Elvatech Ltd. has been developing and producing analytical spectrometric instrumentation since its foundation in 1991. Our XRF spectrometers and analyzers are widely used in various industries as well as in numerous research and academic laboratories worldwide.Spectrometer system s can be divided into two main groups: energy dispersive systems (EDXRF) and wavelength dispersive systems (WDXRF), explained in more detail later. The elements that can be analyzed and their detection levels mainly depend on the spectrometer system used. The elemental range for EDXRF goes from sodium to uranium (Na to U).
An X-ray fluorescence spectrometer (XRF) is an instrument used for elemental analysis of a variety of different materials. Some examples include: metal alloys, precious and exotic metals, plastic, soil, ore, ceramic, paint, paper, mineral assay.In 1913 the elder Bragg built the first X-ray spectrometer, which he initially used to study X-ray spectral distributions. Within several years they were able to use this instrument and Bragg's law to derive the structure of crystals and show the exact positions of atoms. .
