An infrared spectrophotometer is an analytical instrument used to identify materials including organic polymers. Infrared spectrophotometers record the relative amount of energy as a function of the wavelength/frequency of the infrared radiation when it passes through a sample. Therefore, chemical structures of different samples will reflect differences in the IR absorption spectrum allowing for identification of a sample. Unlike a dispersive spectrometer, an FTIR spectrometer or FTIR spectrophotometer is used to simultaneously obtain spectral data of a sample. It does this by using an interferometer to collect the interferogram, also known as the raw data/signal format, which can then be translated into the infrared spectrum of the sample by means of a fourier transform algorithm. As a result, there are many advantages including greater signal-to-noise ratio, high resolution, higher throughput, and a short wavelength limit. FTIR spectrometers can be used in a variety of industries including environmental, pharmaceutical, and petrochemical.

The system performance allows real-time field screening analysis (analysis less than 1 s). The lightweight system includes an infrared radiation analyzer based on the proven Bruker RockSolid™ interferometer. An internal calibration source provides self-test and self-calibration for radiometric measurements. Due to the novel design of the sensor module, the system is resistant to mechanical shocks, vibrations and temperature extremes. It is hardened for field operations in harsh environments.
In order to cover a large range of field application purposes, EM27 has two different system configurations with different sensitivities: Passive mode uses the natural infrared radiation signatures of chemical agents. Active mode detection uses the transmitted light from an active infrared source.
