5 XRD: Quantitative Analysis & Crystal Structure Quantitative Analysis: 65% ZnO, 35% MgO Crystal Structures: © 2007 SHIMADZU 5

6 Crystalline vs Amorphous Solid matter is: Amorphous (random) Crystalline (regular pattern) Smallest volume is a unit cell © 2007 SHIMADZU 6 1 unit cell The Crystal Lattice – La 2 O 3 (cubic)

7 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 non- crystalline from may be ineffective. What effective does temperature have on crystallinity? High temp breaks down crystal? Room temperature vs body temp. © 2007 SHIMADZU 7
