Overview
The JINGHUA 756CRT UV-Visible Spectrophotometer is a high-performance analytical instrument with 1200L/mm UV dedicated grating, imported long-life deuterium/tungsten lamp and photoelectric converter, equipped with C-T monochromator structure, with low stray light, high resolution and good luminosity linearity. The instrument supports automatic wavelength setting, zeroing and transmittance/Absorbance conversion, which can expand a variety of test functions.
Features
1. Adopt 1200L/mm high-performance ultraviolet special grating and imported long-life deuterium lamp/tungsten lamp
2. Imported photoelectric converter and C-T monochromator structure, low stray light, high resolution, good luminosity linearity
3. The wide sample chamber can be extended to a 10cm sample holder to expand the testing range
4. Automatically set the wavelength, automatically adjust 0% T/100% T, T/A without error conversion
5. Automatic correction of wavelength error and Illuminant automatic switching to ensure Test accuracy and continuity
6. With a variety of functions such as luminosity, Basis Weight, standard Linear dispersion, regression equation, kinetics, multi-wavelength, DNA/protein, etc
Principle
The instrument is based on the ultraviolet-visible Spectrophotometric method, spectra-trophotometry principle, and the composite light emitted by the Illuminant is separated by the C-T monochromator structure, and the sample is irradiated with high-performance gratings to select specific wavelength rays of light. Imported deuterium lamps and tungsten lamps provide stable Illuminants, and photoelectric converters detect the intensity of transmitted light, and analyze the concentration and characteristics of substances by measuring the absorption or transmission of light by the sample.
Applications
Chemical analysis, biological testing, drug development, environment monitoring, food inspection, materials science, life science research
Steps
1. Turn on the preheating instrument
2. Place the sample in the sample chamber
3. Automatically set the desired wavelength
4. Perform automatic 0% T/100% T calibrate
5. Select the test mode (Luminosity, Basis Weight, Kinetics, etc.)
6. Start measurement and read data
7. Transfer results via Interface
Notice
• Make sure the instrument is fully preheated before use
• Regularly check the life of Illuminant and replace it in time
• Keep the sample room clean to avoid contamination
• Avoid vibration during calibrating
• Note that the sample concentration should be within the Measurement range
• Correctly Connect Interface Devices
