ANALYSIS APPARATUS FOR OFFENSIVE ODOR RESTRICTED MATERIAL

摘要

PURPOSE: An analysis apparatus for an offensive odor restricted material is provided, to prevent the natural evaporation of sample adsorbed to a concentration pipe by aid of a valve, thereby improving the precision and reliance. CONSTITUTION: The analysis apparatus comprises a collection bag receiving a collected sample; an analyzer(20) provided with a detector(21) for analyzing the sample from the collection bag; a concentration pipe(30) charged with an adsorbent for adsorbing the sample by contacting a needle(31) to the collection bag when it is transported; a bomb(40) charged with a transportation gas for moving the sample adsorbed on the concentration pipe; an impurities removing pipe(50) for adsorbing and removing the impurities contained in the transportation gas of the bomb to allow only pure gas to be transported to the concentration pipe; a three-way valve(60) for selectively converting the direction of the transportation gas passing the impurities removing pipe into the concentration pipe or the analyzer; a bypass pipe(70) for bypassing the transportation gas to the analyzer; and a sample contact pipe(80) for connecting the concentration pipe and the analyzer to supply the adsorbed sample into the analyzer. The concentration pipe(30) has a valve(90) for selectively opening or closing the path.
