READY-TO-USE VOLUMETRIC SOLUTIONS
Titration is the oldest but still the most precise procedure
in chemical analysis. However, such reliable analyses require accurately
adjusted volumetric solutions.
Certificate of Analysis with actual concentration, lot number,
expiry date, stability and traceability to NIST, where applicable.
Titer precision at 20°C - T=l±0.1 %

European Pharmacopoeia Buffer Solutions

Volumetric Solutions ace. 4.2.2 of European Pharmacopoeia
Volumetric solutions are prepared according to the usual chemical analytical
methods. The concentration of volumetric solutions is indicated in terms
of molarity. Molarity expresses, as the number of moles/ the amount of
substance dissolved in 1 litre of solution. The molarity of the volumetric
solutions is determined by an appropriate number of titrations.
The repeatability does not exceed 0.2 per cent (relative standard deviation).
Volumetric solutions are standardised by the methods given in Ph Eur and
accompanied by a certificate of analysis.
The identity of C.PA. Product Codes with  Ph Eur Codes makes

the desired product easy to find.
