What Is a Titrator?
A titrator is a device that can automatically perform various types of titrations. Titration is an analytical method to quantify a target substance in a sample. By slowly adding a standard solution of known concentration to a sample of unknown concentration and measuring the volume required to complete the reaction, the concentration of the sample can be determined.
There are several types of titration, such as neutralization titration, redox titration, and precipitation titration. In ordinary circumstances, titration is performed manually using a burette or other special equipment. However, with a titrator, titration can be performed automatically, including dropping of the solution, determination of the endpoint, and calculation of the concentration.
Uses of Titrators
Titrators can automatically and accurately perform a series of titration operations that are usually performed manually.
Titration is used in the fields of product quality control, analysis, and testing to determine the concentration of a target substance. Since specific components can be accurately quantified, they are used in the purity analysis of compounds, water hardness measurement, and acidity analysis of food products.
Titrators are increasingly being used in research facilities and companies because they cut down on labor hours and enable accurate measurements.
Principles of Titrators
Titration is an analytical operation to quantify a target substance in a sample. By adding a standard solution of known concentration to the target solution and determining the volume required to reach the endpoint, the concentration of the target substance can be determined. Laboratory instruments used in titration operations include conical beakers, burettes, and whole pipettes, which are studied in high school chemistry. An indicator is usually used to determine the endpoint. This is so that the endpoint can be determined by the color change.
Titrators mainly consist of a control panel, burette, stirrer, electrode, and detector. The reagent to be titrated is connected to the burette, and a beaker containing the sample to be measured is placed on the stirrer. Most of the instruments are compatible with the electro-titration method, and the endpoint is determined by measuring the amount of electricity that changes due to the reaction.
