Infrared spectrometers help to identify materials by passing an infrared laser through a sample. The detector then records the relative energy as a function of the wavelength of the infrared radiation when it goes through the sample. This means that different structures will reflect differences in the IR absorption spectrum allowing for identification of a sample. FTIR spectrometers can be used in a variety of industries including environmental, pharmaceutical, and petrochemical. We are always buying and selling used FTIR spectrometers, if you need a specific model, or are looking to sell, don't hesitate to get in touch.
