Optical sensor automating photometric titrations removes guesswork

MEP Instruments introduces a new range of optical sensors designed to automate photometric titrations.

Many titrations are still 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.

Guessing shades of various colours is now no longer needed with the new Metrohm Optrode. Featuring eight different wavelengths for a wide measuring range, the optical sensor is 100% solvent resistant thanks to a glass shaft, and is also very easy to handle.

Typical applications for the new photometric sensors include photometric titrations in accordance with USP and Ph. Eur. (nonaqueous); determination of carboxyl end groups (nonaqueous); TAN/TBN in accordance with ASTM D974 (nonaqueous); chloride in silicone products (nonaqueous); sulphate determination; Fe, Al, Ca in cement; water hardness (total hardness and Ca/Mg); and chondroitin sulphate in accordance with USP.

The Optrode optical sensor can be used on both new and existing Metrohm titration systems as well as on titrators from other manufacturers.

The full range of Metrohm instruments and Metrohm Certified Support is available in Australia and New Zealand at MEP Instruments, a Metrohm and Anton Paar Company. MEP is a joint venture company of Metrohm and Anton Paar set up to serve the scientific industry in Australia and New Zealand with first class products and services.
