Aqueous composition e.g. drill mud, analyzing method, involves determining contribution of water in aqueous composition with measured optical density by programmed processing unit, while calculating spectrum of optical density of water

摘要

The method involves measuring an optical density of an aqueous composition for different wave lengths from a range of wave length comprised in a near infrared field using a reflexive spectroscopy. The contribution of water in the aqueous composition is determined with the measured optical density by a programmed processing unit, while calculating a spectrum of the optical density of the water such that a part of the calculated spectrum corresponds to a part of a spectrum of the optical density measured for the aqueous composition.
