Analytical Development

Chemical characterization of solids and liquids applying and combining a broad range of different techniques, such as chromatography, spectroscopy , spectrometry

Development of analytical methods to solve a broad spectrum of problems

Method validation, e.g. according to ICH guidelines

Full CMC support including QP release

Isolation and identification of trace components from various matrices

E.g., process water, process by-flows, API, drug product, natural products, etc

Solid state investigations

Polymorph, salt, and co-crystal screening

Solubility determinations to fit your development phase

From early discovery to late development

Isolation/separation alternatives Purification of a major or a minor component Chiral separations Isolation of low level impurity/degradation product from

API or drug product Chromatographic purification of material up to ca 300mg by Semi-preparative LC-UV-MS 10g by preparative LC-UV
