Metrohm launched a new generation of photometric electrodes, the main features are as follows: the electrode has a wide range of applications, according to experimental needs, eight wavelengths can be selected, (470, 502, 520, 574, 590, 610, 640 and 660 nm), glass rod design, 100% resistant to organic solvents, and easy to clean after use.

When the potentiometric titration electrode cannot find the correct titration end point, but it is urgent to develop a simple, fast and low-cost experimental analysis method (compared to AAS, ICP-AES), the photometric electrode is undoubtedly a good choice.

A large number of application examples:

        • Photometric titration (non-aqueous system) prescribed by the United States Pharmacopoeia and European Pharmacopoeia

        •Determination of terminal carboxyl group (non-aqueous system)

        • ASTM D974 standard, determination of total acid number TAN/total base number TBN (non-aqueous phase system)

        • Determination of chloride ion content in silica gel samples (non-aqueous system)

        •Determination of sulfate ion content

        •Determination of Fe, Al, Ca ion content in adhesive

        •Determination of total water hardness (total hardness and Ca/Mg　 ion)

        •The United States Pharmacopoeia stipulates the determination of chondroitin sulfate content

        Whether you have a new Metrohm titrator or an old model titrator, you can be equipped with this photometric electrode. There are two power supply methods for the electrode: 1) Direct power supply through the USB interface on the Metrohm titrator (Titrino plus, Ti-Touch, Titrando); 2) If your device is an old model titrator, there is no direct power supply USB interface, then you can choose a USB power converter to directly supply power to the photometric electrode.
