For more than 70 years, molecular spectroscopy is used for the identification of unknown molecules. The infrared absorption spectrum of an organic compound is easy to measure and provides a unique fingerprint. Modern FT-IR instruments can record a spectrum in seconds, and sample preparation is minimal or even unnecessary with modern sampling techniques like (diamond-) ATR. Our company has been involved in the evolution of IR Spectroscopy from the early days. New in our program are the FT-IR Spectrometers from Interspectrum. A wide range of Sampling Accessories completes the program.
