    a diameter of 10 feet (33 meters). Reflectors are economically viable as it requires comparatively smaller domes for storage as they are more compact than the large tubed refractors, as well as reflectors do not inherent the problems relative to absorption of energy as seen in refractors. Problems with resolution due to the wave nature of light can be resolved as the optical telescopes have very high

    of the Columbia River may or may not be contaminated with dangerous metal ions. To test this, The water from the river will be compared to solutions with known metal ions. The two main testing methods for finding ions will be emission and absorption spectroscopy. The presence and, in some cases, amount of the ions in the water will determine whether or not the water is safe for fish. Water safety is a very important thing to know. The residents of Montana may or may not be able to get fish from

  • Degradation Of Polymer Essay

    thermal degradation of polyvinyl chloride (PVC) with time * To compare the various differences between the changes in PVC during thermal oxidation and those induced by thermal degradation * To learn how to use the Fourier Transform Infrared Spectroscopy (FTIR) and UV-Vis spectrometers to obtain information on the changes in the molecule structures over degradation time. 2. Introduction Polymer Degradation Degradation of polymers includes all the changes in the chemical structure and physical

  • Purification And Characterization Of Cellulobiase Essay

    2306 Words  | 10 Pages

    Purification and characterization of Cellulobiase By John Bullock Abstract In this experiment we determined the enzyme activity for cellulobiase. Two buffers were prepared in order to quantitate the proteins using ion exchange chromatography. Protein determination was then carried out using linear regression data. Once the protein determination was done we then selected the correct proteins to run our enzyme assay. When measuring the absorbance in this case, we were measuring the product

  • Spectroscopy Essay

    Spectroscopy and Bodily Fluids Spectroscopy is the study of emission and absorption spectra of materials in order to discover the chemical makeup of a material. Different atoms emit and absorb different characteristic photons. Because the energy and frequency of photons emitted by an atom depend on the differences in energy between these levels, each chemical element emits a distinct set of characteristic photons. Furthermore, Spectroscopy relates to a method of identifying types of body fluids

  • Determination of the Cause of a “Fish-Kill” in the Clark Fork of the Columbia River Essay

    833 Words  | 4 Pages

    samples from the Clark Fork have been taken and will be tested using both absorption and emissions spectroscopy in order to check the levels of group IA and IIA metal ions. When electrons in an element are excited energy is released that can be measured as light. Each element releases different levels of energy that are observed as different wavelengths of light. With the proper equations (E=hv and E=hc/⋋), emission spectroscopy can be used to find the wavelength and frequency of light emitted by the

    CHM2045L.allF13 11/19/2013 Chemistry I lab Initial Lab Report Introduction: The lab report involved my group using spectroscopy to do chemical analysis by finding the absorption at different concentrations and applying chemistry knowledge and understanding to explain interaction of UV-Visible radiation and organic molecules in commercial products. The absorptions are need to carry out the analysis of the food dyes, determine the interaction between matter and radiation and to find the concentration

  • Determination of Fish Kill Essay

    presence of Na+, K+, Li+, Ca2+, Ba2+, Sr2+, Cu2+, and Fe3+ ions. Also you must determine the concentration of each of the ions present in the water sample. By doing so, you can see which ions and how much of it had killed the fish. By using emission spectroscopy of the water sample and the ions. It can be determined which ions are in the water sample. This is done by comparing the peaks of the ions that must be analyzed to the water sample. After burning each aqueous solution and recording its data it

  • Spectroscopy Essay

    Spectroscopy and spectrography are terms used to refer to the measurement of radiation intensity as a function of wavelength and are often used to describe experimental spectroscopic methods. Spectral measurement devices are referred to as spectrometers, spectrophotometers, spectrographs or spectral analyzers. Daily observations of color can be related to spectroscopy. Neon lighting is a direct application of atomic spectroscopy. Neon and other noble gases have characteristic emission frequencies
