Flexible handheld device for easy IR Analysis

With the newly developed CMT IR Analyser, based on attenuated total reflection,  a new chapter of IR spectroscopy is opened in the middle infrared spectral range. Due to the no-moving-parts design, applications even in harsh environmental conditions are made possible. The small size and low power consumption clearly stands out from conventional IR spectrometers available on the market.

IR spectroscopy is a powerful technique for measuring the concentration of organic molecules. The physical effect of infrared light absorption by molecules contained in the sample is being measured. Each molecule absorbs light of a certain wavelength. The intensity of the absorption is a measure of the concentration of the particular molecule.

During the life cycle of an oil, different decomposition and conversion processes occur at the molecular level. A drop of oil acts as an information memory for both equipment and oil condition, which can be read by IR spectroscopy.

Together three interacting mechanisms form the process of oil aging:

  • base oil degradation
  • additive depletion and 
  • contamination

Base oil degradation predominantly is driven by oxidation processes caused by oxygen and heat. Typical oil condition parameters are: Oxidation, AN, BN, nitration, sulphation, ...

Commonly used additives are e. g. anti foaming additives, anti-wear additives and anti oxidants. During oil aging the concentration of additives decreases and degradation products emerge. This oil aging mechanism is being indicated by the concentration of molecules with central ions of zinc, molybdenum, phosphorus, calcium, magnesium, barium or sodium.

Oil contamination is often caused by foreign substances such as water, glycol, diesel, petrol or other oils.

The oil condition sensor of the IR Analyser detects the three major oil degradation mechanism simultaneously. The standard oil condition parameters, that are commonly obtained by laboratory based analysis, are being calculated from the measured IR spectra.

The sensor is based on a spectral apparatus that is  being constructed with no moving parts, which makes it durable and virtually maintenance free. Meaningful oil condition parameters are calculated from the recorded spectra by a previously built oil-specific calibration (chemometric model).

In addition to portable systems for rapid on-site analysis, models for use in the laboratory are available – as well as rugged field installations for inline operation.
