XRD.US provides a full range of powder diffraction services. Our services
range from simple powder diffraction data collection to advanced powder
methods, including ab initio structure determination, quantitative
phase analysis, Rietveld structure refinement, grazing incidence
diffraction, high temperature diffraction etc. Importantly, the outcome of
our services is not what is normally expected from a commercial laboratory. We will provide you with well presented
research grade reports,
suitable for publication purposes. If needed we will perform all the analyses
according to the ASTM. The services which we offer
are, in fact, a piece of scientific work for a fraction of fee usually
charged by university
departments.
If you are preparing proposals for the federal funding agencies, or
a proposal for some beam time at a synchrotron source or at a neutron diffraction
facility, we can help you with the preparation of the sections related to diffraction
methods, experiments etc.

Services |
Brief Description |
| Powder data acquisition |
We will measure the diffraction pattern of your samples as
supplied, size-fractionated or as otherwise instructed by you using following
types of diffraction equipment: (1) Laboratory X-ray diffractometer, (2) Synchrotron radiation source,
(3) Neutron diffractometer.
The raw data files will be collected with
required scan parameters (step size, radiation source, wavelength etc),
ASCII formatted and mailed to you.

| Ab initio structure determination |
Suitable single crystals are not
always available for structure determination. We can try to solve the
structure using only powder data by ab-initio methods. Ab initio
method is often required for promising drug candidates.
