Informacje ogólne

Primary Standards

ROTI®Star Primary Standards for pharmaceutical and food analysis

ROTI®Star Primary Standards are extensively characterised by the analytical methods listed below and are supplied with a Primary Standard Certificate.

The certificate contains:

  • Proof of identity with spectra, e.g. 1H NMR, 13C NMR, MS, UV
  • Content determined with two independent validated methods, e.g. chromatographic purity and quantitative NMR
  • Content of residual solvent determined with two different validated GC methods
  • Water determination by Karl Fischer titration


Reference Standards

The reference standards are offered as powders with good flowability and crystallinity to guarantee efficient handling in the laboratory. All products of this product line are filled in brown glass vials with screw caps and are packed in foil bags. This packaging provides optimum protection against environmental influences, even when stored over a long period of time. The reference standards are delivered as “ready-to-use” portions and are stored under controlled conditions.
