Comparison of measurement of pH in 1:3,5 phosphate buffer

Project Description

A bilateral pilot comparison of measurement of pH in 1:3,5 phosphate buffer by primary method (IUPAC 2002) will be carried out between DFM and IPQ. DFM will produce the buffer solution, ship samples to IPQ and the two institutes will perform measurements within one month of production.

Due to production capacity limitations it is not possible to include further participants.
