ABSTRACT:
The concentration of a hydrocarbon gas in a gas discharged from a drain port is detected by a break-through gas concentration sensor provided in a discharge pipe connected to the drain port. The entire amount of the hydrocarbon gas discharged from the drain port as a result of breaking-through of an adsorbent layer is collected by a break-through gas collecting means, and the entire amount of the hydrocarbon gas collected by the break-through gas collecting means is detected. Thus, in measuring the adsorbing ability of a canister, the concentration of the hydrocarbon discharged from the canister by the breaking-through can be detected with the passage of time and in a stable manner, whereby a measurement value of an excellent accuracy can be provided by a single measurement.
