ELEMENT ANALYSIS METHOD AND ELEMENT ANALYZER IN SAMPLE SUBJECTED TO MELTING TREATMENT IN OXYGEN ATMOSPHERE

摘要

PPROBLEM TO BE SOLVED: To provide an element analysis method and an element analyzer having high measurement accuracy, capable of securing reliability to a measured value, concerning element analysis in a sample subjected to melting treatment in an oxygen atmosphere. PSOLUTION: The element analyzer has a melting furnace 1 for installing the sample S inside and performing melting treatment thereof, an oxygen supply path 1a for supplying oxygen into the melting furnace 1, a secondary treatment system 20 for performing secondary treatment of sample gas delivered from the melting furnace 1, and a gas analyzer 2 for measuring a specific component concentration in the sample gas subjected to the secondary treatment. The element analyzer is characterized by having an adsorption treatment part 3 having activated carbon built in the secondary treatment system 20. PCOPYRIGHT: (C)2008,JPO&INPIT
