Zusammenfassung:	The present invention is one that makes it possible to continuously measure the concentration of hydrocarbon components other than methane and ethane in sample gas, and includes: a first flow path L1 through which the sample gas flows; a first analyzer 2 that is provided in the first flow path L1 to measure total hydrocarbon concentration in the sample gas; a second flow path L2 through which the sample gas flows; a non-methane non-ethane cutter 3 that is provided in the second flow path L2 to remove the hydrocarbon components other than the methane and the ethane in the sample gas; a second analyzer 4 that is provided downstream of the non-methane non-ethane cutter 3 in the second flow path L2 to measure the total methane ethane concentration of the methane and the ethane in the sample gas; and a calculation part 11 that calculates the concentration of the hydrocarbon components other than the methane and the ethane in the sample gas with use of the total hydrocarbon concentration by the first analyzer 2 and the total methane ethane concentration by the second analyzer 4.
