PROBLEM TO BE SOLVED: To provide an analyzer for analyzing elements in a sample capable of obtaining the concentrations of O (oxygen), N (nitrogen) and S (sulfur) or the concentrations of O (oxygen), H (hydrogen) and S (sulfur) by one extraction oven. SOLUTION: The analyzer for analyzing elements in the sample is constituted so that the sample 13 in a graphite crucible 12 is heated and melted while supplying an inert gas into the extraction over 1 and the gas extracted at this time is analyzed to quantititatively analyze oxygen, nitrogen and sulfur in the sample 13. Sulfur is quantitatively analyzed using a non-dispersion type infrared gas analyzer 3 using the absorption of infrared rays. COPYRIGHT: (C)2005,JPO&NCIPI
