Further, there is exploration of utility of XRF to determine the thickness of gold plated on copper substrates up to 6 microns.
For the second experiment, the objectives were to determine the detection limits, accuracy, repeatability and efficiency of a X-ray fluorescence spectrometer (Niton XRF analyzer) in comparison with the traditional analytical methods, inductively coupled plasma optical emission spectrometer (ICP-OES). Further, the experiment also involved applying inductively coupled plasma optical emission spectrometer (ICP-MS) in screening of major and trace elements of environmental samples including estuary soils and sediments, contaminated soils, and biological samples. For the third experiment the major objective was to compare lead concentrations in surface peat samples from the South Pennines (UK) derived using (a)
X-ray fluorescence spectrometry is a core aspect in analysis especially in the field of science and industry application. The concept of XRF lies on the principle that individual atoms, wherever excited as a result of contact with an external energy source, ends up emitting X-ray photons characterized by a a wavelength or energy. In which case, on this basis one can define the identity and quantification of an element present therein by simply counting the number of photons contained in energy from the given sample. Henry Moseley coined the technique, after being led by a discovery of X-ray tube that he applied in bombarding samples containing high energy electrons. Intuitively, Henry ended up with a mathematical relationship that could related the atomic number to the element’s emitted X-ray frequency. The years were followed by eventual development of the instrument leading to a modern XRF instrument that is reliable for analysis ...Download file to see next pagesRead More

The second part X-ray Diffraction (XRD) Powder X-ray
...Most of the x-ray applications base on their ability to penetrate through a material. The ability varies within different objects. For instance, X-rays can penetrate easily through flesh and wood and penetrate less in more dancer substances like bones. The power for the X-ray to penetrate also depends on the energy of the X-ray. X-rays that penetrate more are known as hard X-rays and they have high frequency thus having great energy. On the other hard X-rays that have les penetration power are known as...

X-Ray Powder Diffraction
...?X-Ray Powder Diffraction 503509) Introduction X-Ray powder diffraction is used widely in geological studies for the purpose of identifying the composition of minerals present in different rock formations. This provides a quicker method of identifying crystalline structures when compared to optical light microscopy or scanning electron microscopy. (Marta J.K Flour, 1997) Theory A non amorphous material consists of a three dimensional structure having atoms in a series of planes separated by a distance. When X-Rays are directed on to this structure, part of it is transmitted the specimen, some part is absorbed, a part is refracted and the...

X-ray Fluorescence
...X-Ray Fluorescence Introduction X-rays were discovered by Wilhelm K. Rontgen (1845 – 1923), a German physicist (Shackley 7). These rays have a long history in commercial elemental analysis since the discovery of the correlation between a sample’s atomic weight and the X-rays radiating from it, a fact that enabled Henry G. J. Moseley number elements in 1913 through the observation of K-line transitions as observed in X-ray spectrum. This formed the basis of element identification through X-ray fluorescence spectroscopy by...

X-ray Photons
...X-rays are electromagnetic waves lying between UV radiation and -rays. They were discovered by German physicist, Wilhelm Rntgen, and have wavelength 0.01-10.0 nm and frequency 30-30,000 1015 Hz). Main physical properties of X-rays could be described by the experiments where beam of x-ray photons interact with matter. Monochromatic beam of X-ray photons is directed perpendicularly to the electric and magnetic fields. For simplicity they often consider the electric field only and neglect the magnetic field. From a quantum mechanical perspective a monochromatic beam is viewed as being...

X-ray Exposure Components
...X-Ray Exposure Components of X-Ray Exposure Components The X-ray equipment uses electromagnetic radiations to develop an object’s image, commonly with the intention of envisioning something situated beneath the surface of that object. The radiation emitting from the x-ray machine relies mainly upon kVp (tube voltage), mA (the x-ray tube current), s (exposure time) and cm (the distance between focus and detector). The dosage is defined by these parameters. So the major technical factors that affect an X-ray exposure are time, kVp, mA and...

X-ray crystallography
... X-ray Crystallography Studying the structures of crystalline structures was a challenge in the early days of science. Thediscovery of X-rays eased the struggle for determining the arrangement of cells that form crystals. This was with the coining of X-ray crystallography. X-ray crystallography is a scientific tool used to identify the structure of atoms and molecules. Crystallography is done by use of X-rays and the concept of diffraction of light or electromagnetic spectrum. Crystalline structures have an effect on a beam of incident X-rays and cause them to diffract into different directions. With this diffraction, it I easy to derive the three-dimensional outline or image projection of the density of electrons as profiled... in the...

... Lab Report 18 March The Kinetics of a Diffusion-Controlled Reaction Objective: To determine the rate constant and diffusion diameter of a diffusion-controlled reaction using the technique of fluorescence quenching. Introduction This experiment involved the study of a bimolecular reaction between two different species in solution (anthracene and carbon tetrabromide). A bimolecular reaction is a reaction which occurs mechanistically as A + B products, with a mechanistic rate = k [A][B] (Wright 184). For reactions occurring in solutions, the solvent exerts an effect as a consequence of it being a condensed phase, with its molecules very close together even in case of a chemically inert medium (Arnaut, Formosinho and Burrows 225... ). In...
