DIFFERENTIAL ELECTRONIC NOSE IN ON-LINE DYNAMIC MEASUREMENTS

The paper presents application of differential electronic nose in the dynamic (on-line) volatile measurement . First we compare the classical nose employing only one sensor array and its extension in the different ial form containing two sensor arrays working in differential mode. We show that differential nose performs better at changing environmental conditions, especially the temperature, and well performs in the dynamic mode of operation. We show its application in recognition of different brands of tobacco.
