Introduced at Pittcon 2004, these ready-to-use standards allow the validation of analytical methods in a very simple way
With Primus, Fluka introduces certified primary multi-ion standards.
These ready-to-use standards allow the validation of analytical methods in a very simple way.
Primus standards contain 10mg/kg of each Br-, Cl-, F-, NO3-, PO43-, SO42- (anion solution) or Ca 2+, Li+, K+, Mg2+, Na+ (cation solution).
Two leading institutes - Empa (Switzerland) and BAM (Germany) - together characterise the 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 characterised by their traceability to SI as well as their unique accuracy (measurement uncertainty <0.2%).
Metrohm highly recommends the use of Primus standards for the internal calibration and validation of its instruments.
Each new Metrohm IC system contains a Primus set with multianion and multication standards.
Additional sets are available from Fluka.
