8. Using high-energy long-life flange to locate deuterium lamps and imported tungsten lamps, there is no need for cumbersome optical path adjustment when replacing deuterium lamps.
Principle
The instrument works based on a proportional monitoring dual beam of light optical path system. After the light emitted by the light source is split by the monochromator, it is divided into two beams, one beam passes through the sample and the other beam is used as a reference. The two beams are received and compared by the Detector to accurately measure the absorption of specific wavelengths of light in the sample, and then analyze the composition and concentration of the sample.
Applications
Daily analysis, scientific research
Steps
1. Boot initialization.
2. Set parameters such as wavelength through the touch screen.
3. Use the automatic "0" and "100%" functions to calibrate.
4. Put in the sample and reference, and start the measurement.
5. Select scanning, dynamics, concentration direct reading and other functions as needed for testing.
6. Connect to the PC through the USB interface for data transfer or use optional software to process data.
Notice
• Power supply voltage must be AC220V +/- 22V, frequency 50Hz +/- 1Hz.
• The rated power is 200W, please ensure stable power supply.
• When replacing the deuterium lamp, pay attention to the operation specifications, and uninstall the flange positioning screws to avoid touching the light path.
• The instrument is equipped with a 1cm Colorimetric dish rack as standard, and a Miscellaneous Colorimetric dish rack can be selected as required.
• Optional thermal graphics printer or UVwin8 ultraviolet spectroscopy software can be expanded.
• Pay attention to the operating environment of the instrument to keep its performance stable.
