METHOD OF COMPOUNDS CONCENTRATION DETECTION FOR TROLLY MIXTURE Russian patent published in 2008 - IPC G01N21/35 

FIELD: chemistry.

SUBSTANCE: method implies pumped base oil probing with optical beam at wave length within 960≤λ₁≤1100 Nm perpendicularly to pumping direction; measurement of input and output optical radiation intensity of probed oil; detection of optical density; at that simultaneously coaxially to base beam probation with optical beams at two more wave length within 1520≤λ₂≤1600 Nm relatively to water absorption and 1700≤λ₃≤1800 nm relatively to oil adsorption , optical density of radiation at specified wave lengths is determined, and oil and water concentration is determined under equations set.

EFFECT: provides widening of measuring range of oil water content and high accuracy and ability to perform measurements in pumped base oil in pipeline.
