Tandem spectrometers an on-site analyzer

摘要

Advances in spectroscopic chemo-metrics permits massive used oil data collectionv ery quickly and outside a laboratory environment. An instrument has been developed that sequentially pumps a used oil sample through an infrared spectrometer and optical emission spectrometer to determine wear metals, water, glycol, fuel dilution, soot, oxidation, nitration, viscosity and Total Base Number. By referencing its database, it can identify the source of the internal problems and recommend corrective action within five minutes. The instrument is operable ina non-laboratory environment by non-technical personnel.
