UV-VIS-NIR
Instrument Details
Make : Thermoscientific Nicolet iS50
Principle
The UV-VIS-NIR spectrum is due to the electronic transitions and vibrational modes of the molecule. This is characteristic of a compound. Qualitative and quantitative estimations of compounds are possible by this non destructive technique.
The absorption (A) of a solution at a particular wavelength is given by Beer-Lambert’s law A=ect where c is the concentration of the compound, t is the thickness of the cell and e is the molar extinction coefficient characteristic of the compound at a given wavelength. This principle is used for quantitative measurements.
The Cary 5000 is a high performance UV-Vis-NIR spectrophotometer with superb photometric performance in the 175-3300 nm range. Using a PbSmart detector, the Cary 5000 extends its NIR range to 3300 nm making it a powerful tool for materials science research. The large sample compartment can be expanded to hold large accessories and integrating spheres for spectral and diffuse reflectance. The LockDown mechanism makes it possible to quickly change and position accessories for reproducible results
