HAZARDOUS AIR POLLUTANT COLLECTING METHOD USING A BLOW-THROUGH BAG, CAPABLE OF COLLECTING A LARGE AMOUNT OF SAMPLES FOR A FIXED TIME

摘要

PURPOSE: A hazardous air pollutant collecting method using a blow-through bag is provided to collect a large amount of samples for a fixed time, since the amount of samples, which are condensed in a sealed container, are minimized.;CONSTITUTION: A hazardous air pollutant collecting method using a blow-through bag comprises following steps. Sealed containers are manufactured by size set up in advance. Selected is the sealed container which is the closest to a leak inspection site(S100). The leak inspection site is sealed using an adhesive Teflon tape(S200). The outside air of the sealed container is collected by a pump. An oxygen concentration detector is inserted into the pump, and oxygen concentration value included in the outside air is recorded(S300). The nitrogen gas flows in a nitrogen bombe apparatus inserted to the inside of the valve of the sealed container inlet port. The oxygen concentration is measured by the oxygen concentration detector inserted into the inside of the valve of the outlet port and is recorded.;COPYRIGHT KIPO 2011
