Starting with the initial structure determinations by the Bragg's one hundred years ago and continuing to today, single crystal diffraction is the gold standard for chemical analysis. However, many materials, particularly those newly found, do not form suitable single crystals. Structures can be determined from powder diffraction, but this is not routine. It is greatly facilitated, however, by high quality instrumentation and software. As will be presented, the Advanced Photon Source at Argonne offers several synchrotron powder diffractometers including 11-BM (http://11bm.xray.aps.anl.gov), the country's highest resolution instrument, which can even be accessed by mail. In addition, our open source GSAS-II data analysis suite (http://tinyurl.com/gsasII), the newest available for this work, is designed to make powder diffraction crystallography more straightforward.
