METHOD FOR SPECTRO-PHOTOMETRIC DETERMINING OF CONCENTRATIONS OF DIFFERENT INDICATORS IN BED WATERS Russian patent published in 2006 - IPC G01N21/17 

FIELD: measuring equipment engineering.

SUBSTANCE: in the method sample from oil product well is separated from oil, water solution is cleaned from mechanical admixtures and lightened by centrifuging, received solution is split on even portions, number of which equals to number of determined indicators, and to each portion additional reagents are added for analysis of appropriate indicators, numeric content of separate indicators in source sample is determined by results of optical measurements of each prepared portion of solution relatively to value of natural background level for wave lengths, characteristic for researched indicators. Analysis is performed on basis of results of three optical measurements of each mixture and measurement of concentration of separate indicators in case of their combined presence in sample of bed water is performed by interpolation method.

EFFECT: increased precision of determining.
