Buy Gas Chromatograph Factories - Digital visible spectrophotometer – NANBEI
Buy Gas Chromatograph Factories - Digital visible spectrophotometer – NANBEI Detail:
Product Features
1. Photometric measurement: You can select the single-point test wavelength and test method you need in the range of 320-1100nm to determine the absorbance or transmittance of the sample. You can also directly read the concentration of the sample by entering the standard concentration or concentration factor.
2. Quantitative measurement: Measure the sample solution of unknown concentration through the known parameter factor curve or automatically establish the standard solution curve; with first-order, first-order zero-crossing, second-order, and third-order curve fitting, single-wavelength correction, dual-wavelength absorption, etc. Calibration, three-point method is optional; standard curve can be stored and recalled;
3. Qualitative measurement: Set the wavelength range and scanning interval, and then measure the absorbance, transmittance, reflectance and energy of solid or liquid samples at intervals. It can also zoom, smooth, filter, detect, save, print and other operations on the measured spectrum;
4. Time measurement: Time measurement is also called kinetic measurement. Scan the sample at intervals of the time range of absorbance or transmittance according to the set wavelength point. It can also be calculated by inputting a concentration factor to convert absorbance into concentration or reaction rate.
Enzyme kinetic reaction rate calculation. Various map processing methods such as zooming, smoothing, filtering, peak and valley detection, derivation, etc. are available for your choice;
5. Multi-wavelength measurement: Up to 30 wavelength points can be set to measure the absorbance or transmittance of the sample solution.
6. Auxiliary functions: the cumulative time of tungsten lamp lighting, deuterium lamp, tungsten lamp independent switch, UV-visible light switching wavelength point selection, operating language selection (Chinese, English), wavelength automatic calibration.
