The quality of SINUS products is stated on a certificate of analysis. If the quality corresponds to the requirements of pharmaceutical quality guidelines (European Pharmacopöe, USP, BP, DAB and others), certificates will state these accordingly.
Customized features represent special parameters (e.g. showing limited concentrations of impurities such as uncommon heavy metals when tested) that are necessary for use in specified applications.
In such cases these parameters are also stated on the certificate of analysis for particular batches.
