Determination of Wear Metals and Additives (Soaps) in Lubricating Oils by Atomic Absorption
11 Jan 2013Lubricating and hydraulic fluids are crucial for the proper functioning many machines, most of which are simple carbon-based oils or greases that contain additives in them to prevent wear and abrasion of components, however, under harsh conditions wear metals form in lubricant oils. Determination of these wear metals and their respective levels is important for the proper maintenance and operation of equipment. This application note discusses the advent of microwave digestion technology and the use of the Buck 210VGP system and MEGA-1200 Microwave Digestion system for rapid and economical determination of wear metals and additives in hydrocarbons and lubricants.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
