Overview
The YUE FENG UV756 (PC) UV-Visible Spectrophotometer is a high-performance analytical instrument that uses a newly designed Czerny-Turner optical path to ensure the detection of linear Precision and ultra-low stray light. The host can perform photometric detection, Basis Weight detection, display standard Linear dispersion, and store 100 standard Linear dispersion and 200 detection data.
Features
The spacious sample room can accommodate 5 to 100mm Cuvettes, with a standard 10mm sample holder.
2. The host supports photometric detection, Basis Weight detection, displays standard Linear dispersion, stores 100 standard Linear dispersion and 200 detection data.
3. Automatic calibration of wavelength and automatic power-off data holding function.
4. The main components are imported for easy maintenance.
5. Adopt Czerny-Turner light path design to ensure Precision and ultra-low stray light.
6. Can be directly connected to the printer (optional) to print data or maps.
7. Software functions (optional) include photometric measurement, Light spectrum scanning, multi-wavelength testing, DNA/protein testing, Light spectrum derivative, kinetic testing and Basis Weight testing.
Principle
Based on the ultraviolet-visible Spectrophotometric method, the instrument splits the light emitted by Illuminant (tungsten halogen and deuterium lamps) through an Optical inspection system (aberration grating) to measure the Absorbance, transmittance or concentration of the sample at a specific wavelength. The Czerny-Turner light path design ensures the accuracy of the light path and low stray light for High Accuracy Detection.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food testing, materials science
Steps
1. Turn on the instrument power supply and perform wavelength Automatic calibration.
2. Place the sample in the sample room and use the standard or optional Cuvette.
3. Select detection mode (such as photometric measurement, Basis Weight detection or Light spectrum scanning).
4. Set parameters (such as wavelength, scanning speed) and start measurement.
5. To view the results, you can store data or connect the printer output.
6. After use, turn off the power.
Notice
Make sure the sample room is clean to avoid contamination affecting the test results.
- Precision by calibrating the wavelength before use.
Optional features require additional software or equipment.
- Regular maintenance of major components to ensure instrument performance.
- Pay attention to safety during operation and avoid direct exposure to bright light.
