New Sensor for Photometric Titrations According to USP and Ph Eur
Jul 18 2012
Eight wavelengths for a wide measuring range (470, 502, 520, 574, 590, 610, 640 and 660 nm), 100% solvent resistance due to a glass shaft, and easy handling – these are the key-benefits of the Optrode, the new photometric sensor from Metrohm.
Whenever a potentiometric determination of the equivalence point is impossible, but a simple and fast execution of the analyses with the price advantage of titration (compared to methods like AAS, ICP-AES) is wished for, the Optrode is the first choice.
Application examples are numerous: photometric titrations according to USP and Ph. Eur. (non-aqueous); determination of the carboxyl end groups (non-aqueous); TAN/TBN according to ASTM D974 (non-aqueous); chloride in silicone products (non-aqueous); sulphate determination; Fe, Al, Ca in cement; water hardness (total hardness and Ca/Mg); chondroitin sulphate according to USP.
Both new and existing Metrohm titration systems can be equipped with the Optrode. The power supply comes directly via the USB port of a Metrohm instrument (Titrino plus, Ti-Touch, Titrando). In case of older models without USB port power can also be supplied via an optional USB power adapter.
