Abstract
A syringe for collecting expiration is switched, to be connected by a three-way electromagnetic valve, between an expiration blowing part and a measuring part, so that expiration, blown from the expiration blowing part, is collected in the syringe while replacing old expiration. A switching valve is closed upon completion of exhalation so that end-tidal air is collected in the syringe. Thereafter the expiration sample is introduced into the measuring part from the syringe so that a constant amount of the expiration sample is collected by the measuring part to be introduced into a column.
