XRD and SAXS Services for Characterisation of Pharmaceuticals

DANNALAB offers advanced microstructural characterisation based on X-Ray Powder Diffraction (XRD) and Small Angle X-Ray Scattering (SAXS).

We mostly focus on characterisation of pharmaceutical substances including finished drug products.

Different pharmaceutical substances – API’s, excipients, formulations, dosage forms and drug delivery systems - can be efficiently analysed by use of XRD and SAXS. XRD characterisation is often combined with the analysis of the available patents.

The information delivered by our services could be important for quality of your product.
