| abstract | 1300120 Infrared absorption analysis MOBIL OIL CORP 24 March 1970 [24 March 1969] 14130/70 Heading G1A A sample of oil from a sequence of samples is tested for its viscosity, metal content, and infrared absorption and the results are compared in a computer with evaluation criteria which may comprise limit and trend values to provide information in respect of the engine from which the sample has been taken and to provide a print out of results and probable remedial action. The samples are fed on a table and applied to the test equipment by suction and dipping and the infrared spectrometer which may make a number of absorbance tests at different wavelengths for glycol, water content, oxidation, and nitration includes a number of reference samples which may be brought mechanically and possibly by programme into the system as required. The measuring cell is shaped to provide a thin rectangular sample and its inner walls are grooved as at 44, 45, Fig.6 in order to facilitate more rapid filling and emptying and more efficient purging. The test results are introduced to the computer in digital form and the incoming signals are tested for validity before comparison. A record of the measurements may be made and in connection with infrared testing the speed of the recording medium may be varied in dependence on zones of interest. The arrangement may be controlled by a timer which itself may be programmed and the reports may be stored before print out to economize on printer time. A local computer dealing with simple comparisons may be used in conjunction with a further computer which may be connected by line. Metal content may be measured by atomic absorption, X-ray fluorescence, or neutron actuation. |
