Metrohm Optrode optical sensor for automated photometric titrations

Friday, 13 June, 2014 | Supplied by: Metrohm Australia & New Zealand



Many titrations are often performed manually because regulations require a titration to continue until the colour changes; in other words, the endpoint must not be indicated by a pH electrode or a metal electrode. Such titrations can now be automated with an optical sensor, the Metrohm Optrode.

The optrode features eight different wavelengths for a wide measuring range. It is 100% solvent-resistant due to a glass shaft and is easy to handle. The photometric sensor can be used for many applications.

Typical applications include: photometric titrations in accordance with USP and Ph Eur (non-aqueous); determination of carboxyl end groups (non-aqueous); TAN/TBN in accordance with ASTM D974 (non-aqueous); chloride in silicone products (non-aqueous); sulfate determination; Fe, Al, Ca in cement; water hardness (total hardness and Ca/Mg); chondroitin sulfate in accordance with USP.

The optrode can be used on both new and existing Metrohm titration systems, as well as on titrators from other manufacturers.
