Overview
The JINGHUA 756MC UV-Visible Spectrophotometer is a high-performance analytical instrument, using 1200L/mm high-performance UV special grating, imported long-life deuterium/tungsten lamp and photoelectric converter, equipped with professional C-T monochromator structure, with low stray light, high resolution and good luminosity linearity. The wide sample chamber can be extended to 10cm sample holder, supporting automatic wavelength setting, 0% T/100% T and T/A error-free conversion, suitable for a variety of analytical tests.
Features
1. Adopt 1200L/mm high-performance ultraviolet special grating, imported long-life deuterium lamp/tungsten lamp and photoelectric converter, with professional C-T monochromator structure, low stray light, high resolution, good luminosity linearity
2. The wide sample chamber can be extended to a 10cm sample holder to expand the testing range
3. Automatically set the wavelength, automatically adjust 0% T/100% T, T/A without error conversion
4. Automatic correction of wavelength error, Illuminant automatic switching to ensure Test accuracy and continuity
5. With photometric, Basis Weight, standard Linear dispersion and other functions, scanning scalable regression equation, kinetics, multi-wavelength, DNA/protein and other functions
Principle
The instrument is based on the ultraviolet-visible Spectrophotometric method, spectra-trophotometry principle. The light emitted by the Illuminant is dispersed into monochromatic light through the C-T monochromator structure. After the sample absorbs the light of a specific wavelength, the photoelectric converter detects the transmitted light intensity, calculates the Absorbance or transmittance ratio, and realizes the quantitative analysis of the substance. Automatic wavelength setting and Illuminant switching ensure measurement accuracy and continuity.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food inspection, materials science
Steps
1. Turn on the preheating instrument
2. Place the sample in the sample room and adjust the sample holder as needed
3. Automatically set the wavelength through the control interface
4. Perform automatic 0% T/100% T operation
5. Select Measurement mode (such as Luminosity, Basis Weight, Dynamics, etc.)
6. Start measurement and record data
7. Use Interface to export results
Notice
• Ensure that the instrument is used in a stable environment to avoid vibration and direct light
• Regularly check the life of the Illuminant and replace the imported deuterium/tungsten lamp if necessary
• Keep the sample room clean to prevent contamination from affecting Test accuracy
• Follow the automatic function prompts during operation to avoid errors caused by manual intervention
• Turn off the power in time after use to maintain the normal connection of the Interface
