Understanding Fourier Transform Infrared (FTIR) Spectroscopy

Understanding Fourier Transform Infrared (FTIR) Spectroscopy Fourier Transform Infrared (FTIR) spectroscopy measures additive depletion, contaminant buildup and base stock degradation in lubricants. This type of analysis complements wear metal and other analyses. The principle of the test is that an infrared absorbance spectrum is acquired by passing an infrared beam through a thin layer of…

Sampling Best Practices

  Webinar Replay: Sampling Best Practices Proper sampling is the foundation of any lube analysis program. Irregular sampling procedures and inconsistent sample locations will lead to data that does not reveal problems adequately, or is interpreted to identify a problem that does not truly exist, resulting in unexpected downtime or unnecessary repairs. This webinar will…

What Failed Demulsibility Results Mean

What Failed Demulsibility Results Mean Demulsibility, or more correctly, water separation, is a measure of a lubricant’s ability to separate from water. Lubricants and water have a natural tendency to separate because most basestock molecules are non-polar, while water molecules are polar and will seek each other out instead of mixing with the basestock. Water…

Understanding MPC Results

Understanding MPC Results According to ASTM test method D7843, Membrane Patch Colorimetry (MPC) is intended to serve as a “guide to end-users on the formation of lubricant-generated, insoluble deposits”. The issue, however, is that the results do not seem straightforward. Fundamentally, MPC is measure of the insolubles found dissolved or suspended in the fluid, and…
