A split beam system operating within a wavelength range of 190-1100nm, offer Wavelength Reproducibilit ≤0.4nm combined with low stray light of less than 0.05%T.
Deuterium and tungsten light source deliver superior stability across the full wavelength range. Both types of lamp have self timers and are inexpensive and easy to replace when required.
The monochromator is completely sealed and the optical surfaces can be easily cleaned to maintain optimum reflectivity over the lifetime of the instrument.
A maintenance free high resolution direct stepper drive positions the grating precisely, which ensures reproducible wavelength scanning at different scan speed, thus negating any wavelength peak shift.
The principle of T6U spectrophotometer is based on the absorption of ultraviolet or visible light by chemical compounds, which results in the generation of unique spectra. Spectroscopy is based on the interaction of light and matter. When matter absorbs light, it undergoes excitation and de-excitation, resulting in the formation of a spectrum.
When matter absorbs ultraviolet (UV) radiation the electrons in it are excited. This causes them to transition from a ground to an excited state. It is crucial to remember that the difference in energy between the electron’s ground and excited states is always equal to the quantity of ultraviolet or visible radiation absorbed by it.
According to the Beer-Lambert law, when a monochromatic light beam is incident on a solution containing a substance that absorbs the monochromatic light, the rate at which the intensity of the beam decreases along the thickness of the solution is directly proportional to the concentration of the absorbing substance in the solution and also directly proportional to the intensity of the incident monochromatic radiation.
