Adsorption tube aging instrument

The invention provides an adsorption tube aging instrument, which is characterized in that three mutually independent heating channels are arranged in an aging heating area, seven heating positions are arranged in each heating channel, and a heating rod is independently arranged in each heating channel; a heating rod is independently arranged at the lower part of a sample inlet, and the sample inlet communicates with a sample pipe hole; a nitrogen connector communicates with the three heating channels through three heating switch valves; the nitrogen connector communicates with the sample inlet through a standard sample preparation carrier gas switch valve; an aging temperature controller is connected with the heating rod in each heating channel; and a standard sample temperature controller is connected with the heating rod in the sample inlet. The instrument has the beneficial effects that 21 adsorption tubes can be aged at the same time; only one group or two groups of the heating channels can be opened, so
