types of HWI reference standards

For every intended use we offer you the right reference standard:

Standards for research and development (R&D standards)

Our R&D standards are tested using chromatographic and spectroscopic methods and come with a batch-specific certificate of analysis.

Standards for identity and purity testing (ident-purity standards)

Ident-purity standards come with proof of identity, determined chromatographic purity and a batch-specific certificate of analysis.

Standards for assay (assay standards)

We offer assay standards for pharmaceutical quality control as primary reference standards or working standards derived therefrom.
