BGD 254 UV Vis Spectrophotometer 325nm - 1000nm Wavelength Range

BGD 254 UV-Vis Spectrophotometer

1.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 also can determine the dissociation constant of substances, the stability constant of complexes, the molecular weight identification of substances and the indication of endpoints in microtitration as well as be used as a detector in high-performance liquid chromatography.
1200L/mm grating, C-T type monochromator structure, sample chamber can choose 100mm sample holder, with T, A, C, F and other functions, can be equipped with special software to realize the analysis of data from multiple angles, storage and retrieval more convenient. With RS232 communication interface can be optional printer.
