1. A sulfur chemiluminescence detector, comprising:
a gas passage extending in a horizontal direction a first end of which is configured for insertion of an outlet of a column of a gas chromatograph;
a heating furnace including the gas passage and a first heating means for heating the gas passage;
a reaction cell connectable to a second end of the gas passage and configured to react gas having passed through the gas passage with ozone;
a photodetector configured to detect light emitted from the reaction cell;
a housing which houses the heating furnace, the reaction cell and the photodetector;
a connector provided with an inert-gas introduction tube, the inert-gas introduction tube being fluidly coupled to the gas passage; and
a selectable interface including a first interface and a second interface, the first interface and the second interface each having a column passage and a second heating means,
wherein a length of the column passage and the second heating means in the first interface is shorter than that in the second interface,
wherein when the first interface is selected, the first interface is inserted into a first opening provided in a first wall of the gas chromatograph and the column is inserted into the first opening and the column passage,
wherein when the second interface is selected, the second interface is inserted into a second opening provided in a second wall facing the first wall of the gas chromatograph and the column is inserted into the second opening and the column passage, and
wherein the inert-gas introduction tube is fluidly coupled to the column passage of either the first interface or the second interface.
