Principle
The instrument adopts a proportional dual beam of light design. The light emitted by the Illuminant (deuterium lamp and tungsten lamp) is divided into a reference beam of light and a sample beam of light through a high-performance grating and a photoelectric converter. The absorption or transmission of light by the sample is measured to analyze the parameters such as Absorbance and concentration of the sample. Automatic wavelength correction and scanning functions ensure data accuracy and Repeatability.
Applications
Chemical analysis, biomedicine, environment monitoring, pharmaceutical industry, food testing, materials science
Steps
1. Turn it on and check the status of the instrument.
2. Select the test function (such as luminosity, Basis Weight, or kinetics) through the Touchscreen.
3. Place the sample in the automatic octagonal cell sample holder.
4. Set the wavelength and scanning parameters.
5. Start the test, and the instrument automatically scans and displays the data map.
6. Save or export data and use dedicated software for comparison and analysis.
Notice
• Ensure that the Instrument Operating Environment is Stable to Avoid Vibration and Strong Light Interference.
• Regularly check the life of the Illuminant and replace the deuterium lamp or tungsten lamp in time.
• Test accuracy by calibrating wavelength and transmittance before operation.
• When using dedicated software, back up important data to prevent loss.
When connecting USB devices, ensure compatibility and safe operation.
