Nachweisverfahren und -vorrichtung für chemischen Stoff

摘要

An apparatus for measuring a chemical substance which comprises a decomposition means (10) wherein a substance to be measured which is adhered to an impurity is decomposed and converted to a chemical substance characteristic to the substance to be measured, a chemical substance-measuring means (30), and a filter (50) through which the chemical substance is introduced selectively to the chemical substance-measuring means (30) and which indirectly measures the substance to be measured based on the result of the measurement of the chemical substance. The apparatus can be used for achieving the realtime measurement with high sensitivity of various chemical substances including a chemical substance formed in the form of an adherend to an impurity, e. g. dioxin.
