Title:
HEATING/COMBUSTION TUBE FOR USE IN ANALYSIS OF MERCURY, THERMAL DECOMPOSITION APPARATUS, AND MERCURY ANALYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/073617
Kind Code:
A1
Abstract:
The present invention provides: a heating/combustion tube for use in the analysis of mercury, whereby it becomes possible to eliminate the interference by a substance that co-exists with mercury and analyze mercury with high sensitivity, accurately and with high precision, without the need of using any masking agent, any additive or any gas washing solution; a thermal decomposition apparatus; and a mercury analysis apparatus. This heating/combustion tube (20) is a cylindrical heating/combustion tube (20) which is to be heated for use in the analysis of mercury, and comprises: a sample heating/decomposing section (10) in which a sample (S) is heated and decomposed; an oxidation section (11) into which a fourth period metal oxide (13), which is an oxide of a metal element in the fourth period on the periodic table, is filled; and a treatment section (12) into which a compound of an alkali metal and/or a compound of an alkali earth metal (14) is filled.
