Titrator – FAQs
How do titrators work?
Titrators are used to determine the concentration of a substance (i.e., analyte), which is dissolved in a sample. A reagent (titrant) is added manually or automatically in a known volume and the chemical reaction is monitored. Various sensors are available to monitor the reaction depending on the type of titration you are performing. Metrohm offers sensors for photometric, redox, precipitation, complexometric, surfactant, acqueous acid-base, and non-aqueous acis-base titration.

What is an automatic titrator?
Automatic titration systems perform the titration procedure automatically, including results calculation, sample preparation, and sample series analysis. The steps performed by any automatic titrator from Metrohm are:
- Titrant is added with an automated piston buret that safely controls the delivery of titrant to a precise level.
- The sample is homogenized with a stirrer.
- The electrode detects the titration endpoint, removing subjectivity of color changes.
- Results are automatically calculated and displayed allowing no room for human error.

Which types of indication methods exist?
The most common indication methods for automated titrations are potentiometric and photometric endpoint (EP) determination.
In potentiometric EP determination, the difference in potential is measured: The concentration-dependent potential of a solution is measured using an indicator electrode against a reference potential, which is measured using a reference electrode. Combined sensors including both indicator and reference electrode are also available.
In photometric EP determination, a photometric sensor, such as the Optrode from Metrohm, is used to determine the change in intensity at a particular wavelength of a light beam passing through a solution.
