AUTOMATIC ANALYZING SYSTEM FOR ORGANOCHLORINE COMPOUND

摘要

PURPOSE:To conserve labor and to perform analysis rapidly by automating the reaction and analysis using an apparatus provided with a mechanism preventing the deterioration and decomposition of a reagent deteriorated and decomposed in air for a long time in the analysis of an organochlorine compound. CONSTITUTION:An automatic sampler A having an inert gas filled box part C capable of blocking a reagent from air and a liquid chromatograph part B are connected through a sample injection valve 1. The organochlorine compound set to the automatic sampler A is mixed and reacted with the biphenyl sodium solution being the reagent set to the inert gas filled box part C under stirring and nitric acid and water are added to the resulting reaction mixture to extract a chloride ion and the extract is added to the flow passage system of the liquid chromatograph part B to calculate the concn. of the chloride ion to quantify the organochlorine compound.
