Spectrometry by Wavelength
Spectrometers are instruments that measure the absorption of radiation by a sample. Used in analytical chemistry, atomic physics, and in many industries, such as pharmaceutical and food and beverage, spectrometry is used for sample analysis and quality control. Spectrometers are categorized in part by what wavelengths they are capable of measuring. There are infrared (IR), near infrared (NIR), ultraviolet (UV), and ultraviolet-visible (UV-VIS) spectrometers. IR and NIR spectrometers measure radiation with longer wavelengths than visible light has, and UV spectrometers measure radiation with shorter wavelengths.
Considerations for purchasing a Spectrometer by Wavelength Range
Besides their wavelength ranges, features of spectrometers can vary. Before deciding on the right instrument, consider the sample size needed and the size that can be accommodated, the size of the machine, and the size of the reference library on board to help identify spectra produced by your samples.
