BGD 256 Digital Single-Beam UV-Vis Spectrophotometer
Description
The principle of the spectrophotometer is a light source generated by a continuous radiation light by the dispersion system (monochromator) decomposed into wavelengths of continuous monochromatic light, monochromatic light by irradiation to the sample cell, through the pool of samples will be absorbed by the detection of the intensity of the incident light S and the intensity of the incident light R, the transmittance T = S / R. If the wavelength is continuously adjusted (i.e., scanning), it can be obtained in the biochemical samples on the wavelength distribution of the transmittance, its transmittance on the wavelength distribution and the composition of the sample and concentration related. The transmittance of a biochemical sample is distributed about the wavelength, and the distribution of the transmittance about the wavelength is related to the composition and concentration of the sample. Thus, the composition and concentration of the sample can be determined.
Spectrophotometers are commonly used for substance identification, purity checking, and the study of organic molecular structure. In the quantitative aspect, it can determine the content of each component in compounds and mixtures with complex structure, and can also determine the dissociation constant of substances, the stability constant of complexes, the molecular weight identification of substances and the indication of endpoints in microtitration, and be used as a detector in high-performance liquid chromatography, etc. The spectrophotometer can be used to determine the concentration of a sample.
1200L/mm UV grating, C-T monochromator structure, sample chamber can be extended to 10cm sample holder, automatic wavelength setting, automatic adjustment of 0%T/100%T, T/A conversion. With automatic correction of wavelength error, light source automatic switching and other functions; with photometric, quantitative and other functions; with RS232 communication interface can be optional printer.
