METHOD OF IDENTIFYING AND MONITORING CONCENTRATION NANO-OBJECTS IN DISPERSED MEDIA Russian patent published in 2011 - IPC G01N27/48 B82B3/00 

FIELD: physics.

SUBSTANCE: identification and monitoring of concentration of nano-objects in dispersed media is realised by forming a measurement cell based on a resonance-tunnel structure and analysed medium, plotting the current versus voltage curve of the measurement cell, determining resonance potential values from current maxima of the curve, identifying nano-objects through comparison with the database of resonance potential values and determining concentration of nano-objects from current values for corresponding resonance potential values. Using the method, nano-objects can be identified in a dispersed medium from resonance potential values and concentration of said objects in percentage values of the occupied volume can be determined. High noise-immunity of identification is achieved owing to the need for coincidence of all resonance potential values of nano-objects stored in the database with resonance potential values established from analysis of the current versus voltage curve of the measurement cell which contains the analysed dispersed medium with the identified nano-objects. High accuracy of determining concentration is achieved owing to its calculation on all resonance peaks and further averaging of calculated values on separate peaks.

EFFECT: high noise-immunity of identification, high accuracy of determining concentration, possibility of automating the process of identifying and determining concentration of nano-objects.
