PRETREATMENT EQUIPMENT FOR ELEMENTARY ANALYSIS AND ELEMENTARY ANALYSIS SYSTEM, AND PRETREATMENT METHOD FOR ELEMENTARY ANALYSIS AND ELEMENTARY ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pretreatment apparatus for elementary analysis and a pretreatment method for elementary analysis that can be speedily and easily operated and enable an elementary analysis apparatus to determine a very small amount of elements included in a sample with good sensitivity.;SOLUTION: The present invention relates to a pretreatment apparatus 10 for elementary analysis that performs a pretreatment for analyzing elements included in a sample containing fluorine, the element being an element selected from silicon etc. The pretreatment apparatus for elementary analysis includes: a combustion pipe 1 capable of containing a sample S; a heating furnace 3 for generating a combustion gas by heating the combustion pipe 1 from outside to burn the sample S; an absorption bottle 8 filled with an absorption liquid 9 for absorbing at least some of components included in the combustion gas; a tube 5 for transferring the combustion gas from the combustion pipe 1 to the absorption bottle 8 to bring it into contact with the absorption liquid 9; and a pump 6 and a flowmeter 7. Further, the present invention relates to an elementary analysis system including the pretreatment apparatus 10 for elementary analysis, and an elementary analysis apparatus which takes elementary analysis of the sample S using the absorption liquid 9 obtained by the pretreatment apparatus 10 for analysis.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
