Abstract

The on-site analyzer (10) includes a housing (14). The housing (14) contains an infrared spectrometer (18) and an optical emission spectrometer (24) for testing a sample (12) of oil. A conduit (32) by operation of a pump (40) draws the sample (12) into the conduit (32), and controllably moves the sample (12) to an infrared spectrometer (18) for testing, and subsequently to an optical emission spectrometer (24) for testing. The pump (40) and spectrometers (18, 24) are controlled by a computer (50) for complete automation of testing. The computer (50) performs analysis and diagnosis of the test results from the spectrometers (18, 24) based on sets of known and standard information.
