APPARATUS AND METHOD FOR ANALYZING BREATH GAS MIXTURE FOR HALITOSIS DETECTION

摘要

An apparatus for detecting and separating specific compounds in breath gas mixtures for halitosis analysis consisting of a line (1) for delivering a pressure-controlled neutral gas; a removable connected sample chamber (2) of specific volume for receiving the gas mixture to be evaluated; an electronically controlled valve (8) for injecting the gas sample into the line (1); a temperature-controlled micro-fabricated separation capillary column (4) arranged to receive the gas sample injected into the line (1); a gas sensor (5) at the outlet of the capillary column (4) and a control interface (6) for managing the measurement and evaluating the obtained data.
