testing. e success of this approach led other railroad compa- nies to adopt similar practices. Early elemental analysis relied on atomic absorption spec- troscopy, which was a slow and laborious process. However, in the late 1950s, Dr. Walter Baird introduced the semiautomatic atomic emission spectrometer (AES), also known as the Baird Spectrometer. is device enabled quick and multi-elemental analysis of fluids, reducing testing time from hours to minutes. It initially catered to railroads and large industrial plants but soon found commercial applications. In the late 1960s, the U.S. military faced failures in aircraft due to rolling element bearing fatigue. e existing particle detection technologies, such as ferromagnetic chip detectors and elemental spectroscopy, were ineffective in detecting early- stage bearing wear. To address this issue, Vernon Westcott developed the ferrograph, a laboratory instrument that visually detects and analyzes particles of all sizes. It gained popularity in the military and private sector, leading to the establishment of the International Conference on Advances in Ferrography in 1982. Advancements in oil analysis continued with the intro- duction of Fourier Transform Infrared Spectroscopy (FTIR) to detect oil chemistry and certain contaminants. e field also witnessed improvements in particle imaging software, charge-coupled devices (CCDs) for particle counting, and the emergence of online and onsite testing with portable instruments. As the 21st century progressed, oil analysis technology further evolved, with the development of semi-portable analyzers, handheld IR spectrometers, and the integration of artificial intelligence and the Industrial Internet of ings (IIoT). e future of oil analysis will explore additional topics such as condition monitoring, sampling methods, test selections, and the development of technologies like viscometry, particle counting titration, gas chromatography, flash-point testing, blotter spot chromatography, and grease analysis.
