Spectroscopy , as has been mentioned in previous posts, is the study or measurement of the interaction of matter and electromagnet radiation resulting in spectra (wavelength or frequency of the radiation). Spectrophotometers measure the light energy interactions with a sample to produce spectra.
Spectrophotometers are a common, easy-to-use spectrometer found in many organic analytical chemistry laboratories. They often work on the simple principal of comparing the absorbance or transmission of light through a liquid sample compared to a blank or a standard material. The difference or change from the blank or standard material is used to calculate concentration or a number of other results. The most widely used form of spectrophotometers are UV or UV/Vis spectrometers operating in the UV and visible wavelengths of light from 180 to 800 nm.
