    摘要： PROBLEM TO BE SOLVED: To provide an enrichment analyzer and a method for enrichment analysis capable of highly sensitively and stably analyzing a component difficult to separate an impurity component from a main component by a column as in analyzing arsine as an impurity in a monosilane. SOLUTION: This method comprises a process for enriching primarily the impurity component by making a sample gas flow in the first cooled concentration tube 21, a process for making a primarily enriched gas enriched in the process hereinbefore flow in the second concentration tube 22 to enrich secondarily the impurity component, a process for making a secondarily enriched gas enriched in the process hereinbefore flow into a precolumn 23 to separate preliminarily the impurity component, a process for making a preseparated gas separated preliminarily in the process hereinbefore flow into a main column 24 to separate the impurity component into a single component, and an analytical process for introducing, into an analyzer 17, the impurity component separated into the single component isolated in the process hereinbefore to be analyzed.

    摘要： PROBLEM TO BE SOLVED: To provide a microreactor capable of preventing clogging of a fine channel or a liquid chromatograph even when two substrates where a recess for the fine channel or a recess for the liquid chromatograph is formed are stuck by an adhesive. SOLUTION: This microreactor comprises a lower substrate where protrusions are formed so as to enclose the recess for the fine channel having the width of 0.1-3,000 μm, and an upper substrate where a protrusion insertable into the recess for the fine channel is formed and recesses capable of inserting the protrusions formed on the lower substrate are formed on both sides across the protrusion. The microreactor is formed by inserting each protrusion into each recess on the other substrate and by laminating the lower substrate and the upper substrate, and has the fine channel having the width and the height of 0.1-3,000 μm, formed between the lower substrate and the upper substrate.

    摘要： PROBLEM TO BE SOLVED: To simply prepare a hydrophilic sample for use in analyzing dioxins from a hydrophobic solvent solution of dioxins.
    SOLUTION: The method for preparing the sample for use in analyzing dioxins includes a process of supplying the hydrophobic solvent solution of dioxins refined in a first column 101 to a second column 102 packed with alumina to make the same pass through the column 102, a process of supplying a hydrophilic solvent, capable of dissolving dioxins from a hydrophilic solvent supply part 106, and a process of ensuring the hydrophilic solvent, which passed through the second column 102, through an analyzing sample discharge pipe 107. The hydrophobic solvent solution is, for example, an n-hexane solution and the hydrophilic solvent is, for example, dimethylsulfoxide.
