IRSphinx: small, robust MIR spectrometers for universal use, stationary or portable

Information from absorption – the measuring principle

Infrared spectroscopy (IR spectroscopy) is a physical analytical method, which works with infrared radiation (wave length 2-25 μm). The methods of molecular spectroscopy are based on the excitation of oscillation states in molecules.

IR spectroscopy makes it possible to measure material concentrations in gases, solids and fluids, both qualitatively and quantitatively. The radiation absorption of infrared light is therefore used through molecules in the respective analyte. In the resulting transmission spectrum, the transmission is measured via the wave length of the light. In the process, each molecule absorbs light of a certain wave length and is thus clearly identifiable. The strength of the absorption serves as a measure for the concentration of the molecule.

The measurement device – compact and robust

Comline’s small, portable IRSphinx makes it possible to measure robust and unmoving parts in the particularly informative medium-infrared range (MIR) with a wavelength between 5.5-11 μm (1800-900 cm-1). It can do this directly in process chains or in machines on-site.

Adapted to special applications. The wave lengths 2.5-5 μm (4000-2000 cm-1) and 7-14 μm (1428-714 cm-1) are also available.

The system can be calibrated to a wide range of substances. For this purpose, large databases from laboratory tests (FTIR) are often available, which can be kept in reserve. Alternatively, calibration samples can be measured at various concentrations using IRSphinx, from which a calibration can be made.

Advantages of the IRSphinx compared to NIR spectrometers

  • The fundamental oscillation of the molecular absorbers is measured in the MIR spectral range, which brings an approx. 100-fold stronger measuring signal than in the NIR

  • Lower spectral resolution requirements are needed for the MIR

  • Significantly reduces the problem of waste heat

  • Lower power consumption

  • Lower equipment costs
