Bruker AXS has announced XRDWizard V2.9 support for Variable Counting Time (VCT), a data collection scheme for X-ray powder diffraction, where the measurement time is systematically increased towards higher 2theta angles. As a result, the natural steep intensity fall towards higher 2theta angles is compensated for, leading to dramatically improved data quality for all kinds of profile fitting applications. VCT data typically results
in: greatly enhanced chance for success in structure determination. Atomic coordinates, occupancy factors and (anisotropic) thermal parameters are better determined, especially in the case of light atoms. More stable refinement of atomic coordinates and thermal parameters of light atoms, including hydrogen. Substantially lower RWP
indicating a better overall fit.
