<p>PURPOSE:To always discharge drain stably and continuously, by heating the interior of a drain trap by a heating device and providing an opening part for leaking a small amount of gas to the upper part in the drain trap. CONSTITUTION:The drain D from an electric dehumidifier 1 flows in a drain trap 4 along with a part of sample gas and once falls on a plate 5b. Said drain D is heated by the plate 5b and the dust in the drain D remains on the plate 5b as it is and only the drain D is evaporated to be gradually discharged from an opening part 6a along with the sample gas through a capillary 6. The dust remaining on the plate 5b can be simply removed when the plate 5b is constituted so as to be detached from the drain trap 4.</p> |
