With purity testing, we determine for example whether a batch or sample is free of foreign matter. For this, the PhytoLab team tests the herbal material both for extraneous organic and inorganic constituents, and for microbiological purity – always on the basis of official specifications and our many years of experience.

Purity testing – conventional and instrumental methods

When testing for purity, at PhytoLab we use conventional methods on the one hand, for example in accordance with the European Pharmacopoeia, but we also apply instrumental analysis, such as high-performance liquid chromatography (HPLC) or gas chromatography (GC) with numerous highly selective detectors which enable clear allocation of signals.
