Particle Counting

This technique is typically used for critical hydraulic and turbine systems which have very small clearances, e.g. servo valves. It can also be used to look for early signs of bearing wear or evaluating equipment filter performance.  There are three basic methods used, Automatic Optical Particle Counting (ISO 11500), Optical Microscopy (ISO 4407), and Pore Blockage […]

Oxidation Nitration in Used Oil Analysis

Oxidation and Nitration in Used Oil Analysis

Both oxidation and nitration can be determined using the Fourier Transform Infrared (FTIR) method, which is also used to determine water content as discussed in a previous article.  As you can see from the FTIR scan below both oxidation and nitration give individual peaks from which their level can be determined. There are various FTIR methods […]

Water Content in Used Oil Analysis

Water contamination in oil can be extremely detrimental as it can cause any of the following: Rust/corrosion Sludge formation Increase in oil oxidation Decrease in fatigue life (bearings, gears) Increased wear Reduced additive protection Filter plugging SourcesWater contamination can come from various sources such as: Condensation Low temperature engine operation Inter/after cooler of air compressors […]
