IC eluents and standards

With PRIMUS, Fluka (Sigma-Aldrich) introduces certified primary multi-ion standards to the market. These «ready-to-use» standards allow the validation of analytical methods in a very simple way. PRIMUS standards contain 10 mg/kg of each Br^-, Cl^-, F^-, NO₃^-, PO₄^3-, SO₄^2-.
Two metrological institutes – EMPA (Switzerland) and BAM (Germany) – together characterized primary materials and issue a joint certificate. The solutions are produced at EMPA using the facilities of their metrological laboratories. This is why PRIMUS standards are characterized by their traceability to SI as well as a unique low degree of uncertainty of <0.2%.
