Automatic analysis method and apparatus for trace amount and ultra trace amount of various halogen and sulfur

摘要

PROBLEM TO BE SOLVED: To prevent a crossover between analysis samples from reducing the analysis accuracy, especially in analysis of an ultratrace sample, in an automatic analysis method and device of various halogens and sulfur using a combustion-ion chromatograph method.SOLUTION: Clean air is introduced, toward the upstream side, into an outlet on the downstream side of combustion decomposition gas of an analysis sample from a combustion apparatus, adhesion of combustion decomposition products on the downstream side is reduced, and adhering decomposition products are removed to the outside.EFFECT: An ultratrace sample can be accurately analyzed.SELECTED DRAWING: Figure 1
