Reducing member, analysis device, and analysis method

Abstract

Provided is an analysis device and an analysis method which, while solving the problem of column plugging, carries out continuous analysis of nitrogen in a sample without use of cadmium that causes environmental pollution. The problem is solved by an analysis method including: a sample introduction step of introducing a sample into a tube; a reduction step of reducing, to ammonium ions, nitrate ions and nitrite ions in the sample being transferred in the tube; and an analysis step of analyzing the ammonium ions in the sample which have been generated in the reduction step. In the reduction step, the nitrate ions and the nitrite ions in the sample are reduced by transferring the sample in a hollow tube in which at least an inner wall surface is made of zinc.
