PORTABLE ELECTRONIC NOSE SYSTEM, WHICH ACCURATELY DETECTS SMELL, EVEN WHEN AN OLFACTORY IS CONTAMINATED

摘要

PURPOSE: A portable electronic nose system, which accurately detects smell, even when an olfactory is contaminated, is provided to rapidly detect gas in the long time use by correcting a result by comparing a result measured in a sample cell and a result measured in a standard cell.;CONSTITUTION: A portable electronic nose system comprises a standard cell(300), a first olfactory sensor(200), a sample cell(500), a second olfactory sensor(600) and a controller(800). An air from which measurement target gas feeder is removed passes through the standard cell. The first olfactory sensor measures the gas density of the air passing through the standard cell. The sample cell passes through the measurement target air. The second olfactory sensor measures the gas density of the measurement target air passing through the sample cell.;COPYRIGHT KIPO 2011
