UV transmittance analyzerIt is a device used to measure the transmission of ultraviolet (UV) light through specific materials or substances.

workflow

1. Light source emission: emits ultraviolet light within a certain wavelength range through a UV light source. Common UV light sources include mercury lamps, xenon lamps, etc., which can provide stable and uniform UV output to ensure the accuracy of test data.

2. Sample function: When the test sample is placed in the optical path, its ultraviolet transmittance may vary due to factors such as material properties, thickness, and surface treatment. When ultraviolet rays are irradiated onto the sample, some of the light will be absorbed, some will be reflected, and the rest will pass through the sample.

3. Spectral analysis: A spectral analyzer is used to measure the intensity of ultraviolet light after penetrating the sample, which can cover different bands of ultraviolet light and provide detailed transmission characteristic data.

4. Data processing: Obtain the ultraviolet transmittance by calculating the ratio of the original ultraviolet intensity to the transmitted ultraviolet intensity. This ratio can be the transmittance of different wavelengths or the transmittance of a specific wavelength band, depending on the testing requirements.

This device can be used for the identification and structural analysis of compounds in chemical research. By measuring the absorption characteristics of substances in the ultraviolet light band, the functional groups and molecular structures of compounds can be inferred; In biological research, it is used for the determination of proteins and nucleic acids, such as the analysis of protein content, structural characteristics, and nucleic acid content and purity.

　　UV transmittance analyzerIn industries such as plastics, glass, and coatings, it is used to test the UV transmittance of materials, optimize product formulations and production processes, and improve the UV aging resistance of products; In the textile industry, the UV transmittance and UV protection factor (UPF) of textiles can be measured, providing a basis for the research and quality control of sunscreen textiles.
