high frequency electronic nose sensing and method for determining the quantitative and qualitative composition of a gas or gas mixture through it.

摘要

high frequency electronic nose sensing and method for determining the quantitative and qualitative composition of a gas or gas mixture through it. The present invention relates to an electronic nose comprising a set of redundant blocks gas sensors that alternate air intake smell, so that while a sensor block performs measurements, the other aiming clean air with order to restore olfactory sensitivity, so you can take quick measurements. Each block is housed in a separate chamber and comprises an array of sensors sensitive to different volatile substances, which, along with concentrations, can recognize a variety of odors. The present invention also relates to a method for determining the quantitative and qualitative composition of a gas or mixture of gases using such electronic nose.
