METHOD FOR IDENTIFYING LIQUID AND GASEOUS SUBSTANCES Russian patent published in 2006 - IPC G01N33/02 G01N33/14 

FIELD: technology for determining authenticity of liquid and gaseous substances, possible use in food and perfumery industry, and also during ecological control-related operations.

SUBSTANCE: method includes comparing characteristics of identified sample to characteristics of standard samples. As characteristics, response sets of chemical sensors array x_i, i=T,n are used for identified and standard samples. Processing of aforementioned responses is performed using three different identification algorithms: statistical, neuro-network-based and self-organizing, match criterion is coincidence of not less than two positive results for all three algorithms.

EFFECT: high identification reliability and shorter time required for analysis operation.
