Lattice stress & strain 4. % Crystallinity XRD POLYCRYSTALLINE SAMPLE Phase ID: Three of the 5 forms or Titanium (TiO2) 4 Anatase Rutile Brookite © 2007 SHIMADZU XRD: Quantitative Analysis & Crystal Structure Quantitative Analysis: 65% ZnO, 35% MgO 5 Crystal Structures: © 2007 SHIMADZU Crystalline vs Amorphous Solid matter is: Amorphous (random) Crystalline (regular pattern) Smallest volume is a unit cell The Crystal Lattice – La2O3 (cubic) 1 unit cell 6 © 2007 SHIMADZU Percent Crystallinity of Sample Crystalline and non-crystalline (amorphous) samples scatter x-rays differently so the percent of each can be measured. Drugs in the crystalline from may be effective for the problem, but in the noncrystalline from may be ineffective. What effective does temperature have on crystallinity? High temp breaks down crystal? Room temperature vs body temp. 7 © 2007 SHIMADZU Principal of X-Rays 8 © 2007 SHIMADZU Excitation of Electrons: X-Ray vs UV-Vis-IR X-Ray: Excitation of Inner Shell Electrons UV-Vis-IR: Excitation of Outer Shell Electrons Ionization E2 E1 Excitation state E0 Light of frequency v Electron Atom ic nuclei 9 © 2007 SHIMADZU Spectra: Wavelength & Electron Volts (eV) WAVELENGTH SCALE ENERGY SCALE 0.7 0.7 0.6 0.6 0.5 0.5 0.4 0.4 Absorban ce Absorbance 0.3 0.3 0.2 0.2 0.1 0.1 0 300.0 320.0 340.0 360.0 Wavelength (nm) 10 380.0 400.0 RawData ... 0 3.100 3.300 3.500 3.700 3.900 4.100 eV © 2007 SHIMADZU Types of X-Rays for EDX 11 © 2007 SHIMADZU EDX Series EDX-GP EDX & mEDX 12 © 2007 SHIMADZU EDX Schematic 13 © 2007 SHIMADZU Components of EDX-720/800/900 Liquid N2 Dewar (720/800) Sample Chamber Detector and MCA X-ray tube 14 © 2007 SHIMADZU Question 1a: What Elements Need to be Measured? 15 © 2007 SHIMADZU Question 1b: What Level Need to be Measured? 16 © 2007 SHIMADZU Question 2: Will Viewing Area of Sample Change?
