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.
