Optrode –

Titration in a new light Photometric sensor

• Eight wavelengths: 470, 502, 520, 574, 590, 610, 640 and 660 nm

• 100% solvent resistant

• Compact and space-saving





Photometric titration: benefi ts and applications Titration with a photometric sensor is a widely used me -

• simple and fast performance of measurements is 02

thod of titration. It is based on color changes at the equi-important

valence point and is used primarily when

• the end point of manual titration still has to be determined visually

• potentiometric determination of the equivalence point is not possible

• a standard method specifies photometric indication

• the lower costs of titration compared with more expensive methods (e.g. AAS, ICP-AES) matter Application examples

• 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

Titration of chondroitin (USP) at 660 nm





Advantages of the Optrode

• Eight wavelengths: 470, 502, 520, 574, 590, 610, 640 and 660 nm 03

• 100% solvent resistant

• Compact and space-saving

• Very easy cleaning

• Easy change of wavelength (either manually or when used with tiamo 2.5 software)

• Can be used with Titrino, Titrino plus, Ti-Touch and Titrando Straightforwared setting of the wavelength a) Straightforward switching between eight wavelengths.

b) Simply touch the magnet symbol on the head of the electrode with the supplied magnetic stirring bar ...

c) ... and the next wavelength is set already!





Highly compatible

due to the USB interface

Both new and existing titration systems can be used with the Optrode. Power is supplied directly via the USB port of a Metrohm instrument (Titrino plus, Ti-Touch, Titrando, USB sample changer). In the case of older models with-out a USB port, power can also be supplied via an optional USB power adapter.

Fully traceable measurements with tiamo 2.5

With tiamo 2.5, the wavelength can be set as a titration parameter, which means there is no more risk of using the wrong wavelength or changeing it inadvertently.
