X-ray powder diffraction data is routinely collected in the pharmaceutical industry in support of solid form development, regulatory submissions, patent applications and lot release. Much of the information encoded in diffraction patterns goes untapped because the data is treated merely as a qualitative fingerprint of the specimen. Quantitative interpretation methods, including indexing, may be used to glean additional information from diffraction data.

Indexing gets its name from the assignment of Miller index labels (hkl) to each of the peaks in a diffraction pattern. The size and shape of the crystallographic unit cell is determined as part of the indexing procedure, which is often more useful than the Miller indices themselves. Applications of indexing include pure crystalline phase identification, stoichiometry estimation, and variable hydrate analysis, among others. Although indexing software is available, successful indexing requires good quality data and a skilled analyst to differentiate good solutions from false positives.

Join this webinar to learn why indexing is a useful tool to glean additional information from X-ray powder diffraction data. The expert speaker will discuss the applications of indexing, including demonstrating pure crystalline phase identification, stoichiometry estimation and variable hydrate analysis. Advice for necessary data quality and analyst skill requirements for successful indexing will be provided.
