Check of lubrication oils
IR spectroscopy can be used for the routine monitoring of degradation by-products, contaminants and additive levels in used lubricating oils. The lower cost of modern Fourier transform (FTIR) systems, along with the ability to obtain higher quality data rapidly has made this technique attractive for routine analysis applications. As the need for obtaining quicker analysis results or for routine monitoring of in-service lubricants increases, spectroscopic techniques such as FTIR will gradually replace various time-consuming and tedious traditional wet chemical and physical analysis methods. Recently, the ASTM has adopted a new standard practice E2412 entitled; “Standard Practice for Condition Monitoring of Used Lubricants by Trend Analysis Using Fourier Transform Infrared (FTIR) Spectrometry” illustrating the increased application of FTIR spectroscopy in this field.
