Analysing New and Old Motor Oils

The Pearl™ liquid transmission accessory makes the IR spectral measurement of even the most viscous liquids quick, easy and highly repeatable.

Service oils, like Castrol’s Magnatec engine oil, are designed to minimise wear-and-tear in engines. Over time the oils pick up elemental metals, soot and other contaminants which visibly spoil the oil.

IR spectral analysis can help determine which contaminants are present, as well as what kind of chemical degradation has occurred in the oil. Traditionally, a vertically mounted cell was the go-to method for loading viscous or sticky fluids. However, this approach leads to problems with sample loading, consistent pathlengths and cell clean-up.
