Laboratory colorimeter — efficient measurement of color intensity

A laboratory colorimeter is a device designed to measure the color of samples by analyzing their spectral characteristics. It is used in studies that require evaluating the color properties of substances or solutions. The device determines content, identifies various compounds, and helps control quality and analyze the stability of preparations. In medicine, it is used to measure substance concentrations and determine the levels of biomarkers.

Features of the colorimeter

The basis of the work of the colorimeter is the determination of the color characteristics of samples using light radiation. The device consists of a light source, filters or monochromators, optical elements, registration detector. The functioning of the device is carried out in stages:

1. A lamp, LED or laser emits light of different wavelengths that pass through the sample.

2. Filters absorb the light of certain wavelengths, leaving only the wavelength required for measurement. Monochromators are able to select the desired wavelengths by separating the light into components using a grating or prism.

3. The optical components (mirrors, light guides) direct the light stream to the sample.

4. Light passing through the sample interacts with structures and molecules. Some wavelengths are absorbed and others pass through, depending on the color of the sample.

5. A detector records the intensity of the light that has passed through the sample.

The data recorded during the study is processed using the colorimeter software. Most often, the absorption intensity in a particular wavelength interval is compared to the reference values to determine the color characteristics.

Which colorimeter to buy

A colorimeter, despite its cost, should meet the needs of the laboratory. Before buying an instrument, it is important to consider a number of factors:

• the purpose of the research;

• type of instrument (portable or stationary);

• accuracy and resolution;

• calibration capability;

• housing features;

• availability of additional functions.

Constant calibration support allows for standard settings for specific samples, ensures high accuracy, and compensates for operational distortions. Most modern models can save measured data, generate reports, and provide opportunities to analyze color characteristics.
