Optrode – new sensor from Metrohm for photometric titrations according to USP and Ph. Eur.

publication date: Apr 24, 2012
 | 
author/source: Metrohm AG

Metrohm OptrodeEight 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 EP (non-aqueous)
  • determination of the carboxyl end groups (non-aqueous)
  • TAN/TBN according to 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 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.
