  • METHOD AND TEST KIT FOR THE DETERMINATION OF IRON CONTENT OF IN-USE LUBRICANTS
    Publication number: 20090227035
    Abstract: The present invention relates to a method to determine the iron content of in-use lubricants by means of visible spectroscopy. The invention further relates to a test kit using the method. The test may be conducted on-site. The method of the present invention provides an accurate alternative to the standard Plasma-Atomic-Emission spectroscopic technique (ICP-AES), which must be done in a laboratory. One of the application areas is iron measurement of in-use lubricants having a Base Number up to 75 which are possibly contaminated to a high extent with soot, ash, metal debris etc.
