1. An apparatus for collecting high temperature gas, comprising:
a sample tube extending in a first direction, the sample tube being configured to accommodate a sample in a sample accommodating space inside the sample tube;
a first stopper coupled to a first end of the sample tube, the first stopper having an inlet extending therethrough, the inlet configured to receive an injection therethrough of a carrier gas into the sample accommodating space;
a second stopper coupled to a second end of the sample tube, the second stopper having an outlet extending therethrough, the outlet configured to receive a discharge therethrough of an analysis target gas generated in the sample accommodating space;
a heating furnace configured to heat the sample, the heating furnace accommodating the sample tube in a heating space therein with the first stopper and the second stopper disposed outside of the heating furnace,
a carrier gas supplier connected to the inlet via a first flow conduit and configured to supply the carrier gas to the sample accommodating space;
a plurality of gas collectors each configured to receive and collect therein a respective portion of the analysis target gas generated in the sample accommodating space;
an opening and closing part connected to the second end of the sample tube via a second flow conduit and configured to receive the analysis target gas of the sample accommodating space through the second flow conduit, the opening and closing part being configured to selectively deliver each respective portion of the analysis target gas to a corresponding one of the plurality of gas collectors;
a carrier gas preheater provided in the first flow conduit and configured to preheat the carrier gas passing through the first flow conduit; and
a mass flow controller provided upstream of the carrier gas preheater on the first flow conduit and configured to control a flow rate of the carrier gas injected into the sample tube.
