Bruker AXS DIFFRAC.TOPAS is a comprehensive software package for whole-pattern fitting and Rietveld refinement of powder diffraction data. It supports quantitative phase analysis, crystal structure refinement, and microstructural characterization such as crystallite size, microstrain, and preferred orientation. Using a Fundamental Parameters Approach to model instrumental effects, TOPAS delivers robust peak-shape and background modeling for high accuracy. It accommodates Le Bail and Pawley methods, sequential and parametric refinements for in situ studies, and batch processing for high-throughput workflows. The platform works with laboratory, synchrotron, and neutron datasets, provides a flexible scripting language for automation and custom models, and integrates with common file formats and Bruker diffractometers. Suitable for both routine QC and advanced research, it combines an intuitive interface with powerful modeling to produce reliable, reproducible results.
