Principle
The instrument uses a dual beam of light and a CT-type optical path system. After the light emitted by the light source is split by the monochromator, it is divided into two beams, one passing through the sample and the other serving as a reference. A dynamic feedback proportional recording photometry system compares the intensities of the two beams to accurately measure the Absorbance or transmittance of the sample at a specific wavelength.
Applications
Organic chemistry, biochemistry, product analysis, food inspection, environment protection, life sciences
Steps
1. Photometric measurement: measurement of the sample's Absorbance and transmittance at the specified wavelength; multi-wavelength fixed-point testing can simultaneously determine multiple wavelengths.
2. Quantitative analysis: Automatically establish standard Linear dispersion, can choose first-order and first-order zero-crossing linear regression, second-order and third-order Linear dispersion fitting, can choose single wavelength correction, dual wavelength correction, three-point method; can store standard Linear dispersion for subsequent calls.
3. qualitative analysis: Light spectrum scanning can be performed, the scanning speed can reach 3500nm/min; the scanning speed can be adjusted, and the position of the color filter can be fine-tuned; the map processing methods include scaling, smoothing, filtering, peak and valley detection, etc.
4. Kinetic analysis: Perform enzyme kinetic reaction rate calculation; provide a variety of map processing methods such as scaling, smoothing, filtering, peak-valley detection, and derivation.
5. DNA/RNA, protein testing: Built-in special calculation formulas to directly obtain the final results.
6. Optional dedicated PC anti-control workstation with USB Interface connection or PC analyst software with GMP function to enhance functions and data processing capabilities.
Notice
• The instrument adopts socket deuterium lamp and tungsten lamp. Optical inspection and debugging are eliminated when changing the lamp, but attention should still be paid to the operation specifications.
• The instrument supports remote control, but the effective control range of Bluetooth is recommended to be within 3 meters to ensure stability.
• When using Wi-Fi/Bluetooth or Email for data transmission, it is necessary to ensure the security and stability of the network environment.
When performing data storage or format conversion, please follow the instrument operation guidelines to avoid data loss.
• Optional PC software has audit trail function, if you need this function, please confirm the option.
• The instrument supports online upgrade. It is recommended to back up important data before upgrading.
• The instrument weight is 29kg, and attention should be paid to safety when moving or installing.
• To ensure the stability of the Optical inspection system, severe vibrations should be avoided, although the instrument base is designed to withstand transport vibrations.
