Correction Table Determination for Converting between Atomic Absorption and Atomic Emission Spectrometer Readings.
Abstract
Atomic Absorption (AA) spectrometers and Atomic Emission (AE) spectrometers are currently used by various oil analysis programs to measure the concentration of certain critical wearmetals present in oil samples. This concentration is usually expressed in parts per million (PRM) of the wearmetal being measured. The oil samples are taken from machinery, such as engines and gearboxes, and the wearmetal concentration monitored in an attempt to detect mechanical trouble developing in the oil source. The AA spectrometers and the AE spectrometers have been observed to give significantly different concentration readings for the same used oil sample. This paper proposes regression analysis to estimate correction tables to relate AA readings to AE readings for a given element and a given source of oil. These correction tables would allow oil samples from a piece of machinery to be sent to the nearest available spectrometer regardless of type.
