Described is an apparatus () for measuring odours comprising: a measuring chamber (); an intake duct () having two ends, an inlet end () in communication with the outside environment and an outlet end () in connection with the measuring chamber; at least one sensor (), positioned inside the measuring chamber () and designed for measuring the olfactory properties of a gas; a control unit () designed for processing signals coming from the at least one sensor () and providing a parameter representing the odours measured in the gas to be analysed; a suction device (), positioned inside the intake duct () and designed to circulate the gas inside the apparatus (); a cleaning device designed for restoring the characteristics of the at least one sensor () following a measurement, wherein the cleaning device is designed for generating ozone inside the apparatus ().

Apparatus and method for measuring odours

Method and device for the analysis of a gas sample; the method provides for the sample to be conveyed from an inlet along a feeding duct and from the feeding duct, divided into equal portions, along a plurality of passage channels and through a plurality of detecting stations; in the area of each detecting station a sensor is arranged, which detects a different characteristic of the sample; the gas sample portions are conveyed directly and precisely onto the sensors so as to increase the speed and sensitivity of the detection.

Method and device for the analysis of a gas sample; the method provides for the sample to be conveyed from an inlet () along a feeding duct () and from the feeding duct (), divided into equal portions, along a plurality of passage channels () and through a plurality of detecting stations (); in the area of each detecting station () a sensor () is arranged, which detects a different characteristic of the sample; the gas sample portions are conveyed directly and precisely onto the sensors () so as to increase the speed and sensitivity of the detection.

Method for monitoring the odorous emissions of a plurality of zones () of a given site (); the method provides for the use of an electronic nose, and comprises a plurality of selective feeding steps, during each of which a respective sample coming from a relative zone is selectively conveyed to the electronic nose so as not to convey other gas samples coming from other zones to the electronic nose; according to some aspects of the invention, the selective feeding steps are repeated several times and the order of succession of the selective feeding steps is modified so as to control zones of particular interest more often.

Method to monitor odorous emissions

A method for detecting the composition of an unknown gas mixture (M) through an electronic nose () equipped with a measuring chamber () that houses at least one sensor comprises the steps of: calibrating a sensor by feeding a known gas mixture (M) into the measuring chamber (); feeding the unknown gas mixture (M) into the chamber (), while keeping the unknown gas mixture (Mine) in a predetermined desired state; and detecting the composition of the unknown gas mixture (M) by means of the sensor.
