摘要: PROBLEM TO BE SOLVED: To enhance the detection capacity of carbon-nitrogen stable isotope ratio, or like, an elemental analyzer. SOLUTION: This pretreatment device 2 for analyzing element is constituted so as to form a measuring gas in sample by analyzer 3 and includes autosampler 21 supplying sample, oxygen cylinder 5 reaction gas, combustion part 22a burning supplied from gasify same, oxidizing pipe 22 provided on downstream side having oxidation column 22b, which agent 23 placed reducing 24 25 placed. The formed make flow channel cross-sectional area S1 larger than S2 22d 22b. that S3 smaller 22a. COPYRIGHT: (C)2008,JPO&INPIT
