Overview
The JINGHUA 723 (automatic) visible spectrophotometer is a high-performance analytical instrument with a C-T monochromator structure, 1200L/mm grating, imported tungsten lamp and photoelectric converter to ensure low stray light, high resolution and high luminosity linearity. The instrument has automatic wavelength setting and correction function. Wavelength range 320~ 1000nm, suitable for a variety of sample measurements.
Features
1. High-performance low-stray light 1200L/mm grating and C-T monochromator structure
2. Imported tungsten lamps and photoelectric converters ensure low stray light, high resolution, high luminosity linearity
3. Large sample room, optional 5cm and 10cm sample holders to meet different needs
4. Automatic setting of wavelength and professional automatic correction of wavelength error function
5. The wavelength drive mode is automatic and easy to operate
Principle
The instrument is based on the Spectrophotometric method, spectra-trophotometry principle, and the Illuminant is separated into monochromatic light by a C-T monochromator. After the sample absorbs the specific wavelength light, the photoelectric converter detects the transmitted light intensity, calculates the Absorbance or transmittance, and realizes quantitative analysis.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food inspection
Steps
1. Turn on the preheating instrument
2. Automatically set the desired wavelength
3. Place the sample in the sample room
4. Read and record measurement data
5. Export data via USB or RS-232 interface
Notice
• Ensure that the instrument is used in a stable environment to avoid errors
• Periodically calibrate wavelength and transmittance Precision
• Clean the sample room after use to prevent contamination
• Avoid direct light and violent vibration of the instrument
