WebUV/VIS/NIR spectroscopy is generally used to determine analyte concentrations or the chemical conversion of a component in solution. The technique measures the absorption of light across the desired optical range. A sample is dispensed into a cuvette and placed in the path between the optical light source and a detector. WebIf the spectrometer has a large spectral range, it may also have filters to stop higher order light from reaching the sensor. Most optical spectrometers operate over the UV, visible, and infrared (or near-infrared) regions of the electromagnetic spectrum. Spectrometers can be designed and built using a number of different optical configurations.
