METHOD FOR ANALYZING AND/OR IDENTIFYING LIQUIDS Russian patent published in 2005 - IPC

Abstract RU 2249811 C2

FIELD: analytical methods.

SUBSTANCE: method is based on specific physicochemical feature of combination of impurity traces, which determine composition of product, said feature being capacity of absorbing and reemitting optical emission (luminescence). According to invention, one accumulates files of spectral-luminescent characteristics of product being identified and reference product. Identification procedures allow one to follow minor deviations of characteristics in liquid composition.

EFFECT: increased identification efficiency.
