Optical determination of amount of soot in oil sample |
摘要 |
Method and apparatus for determining the concentration of optically attenuating materials in fluids, such as soot in diesel engine lubricating oils. An optical cell is employed in the form of a very thin tapered sample volume which is inserted into a light beam. The attenuation of the beam is measured at a plurality of locations along the varying thickness of the sample.
