Abstract
PURPOSE: To enable to catch very small amount of components in air quickly and simply without measuring the air to be inspected, by providing the concentrating tube enabling the equilibrium of concentration for objective materials, in the air constant temperature vessel which can be make temperature control of room temperature to about 200°.
CONSTITUTION: The power supply for the constant temperature vessel 1 is activated, and the temperature of the vessel 1 having the thermometer 10 is controlled to a given temperature. After the temperature of the vessel 1 is stable at the set temperature, the suction pump 5 outside the vessel 1 is operated, and the air to be inspected is introduced to the concentrating tube 2 provided in parallel in the reflection plate 9 for temperature uniform distribution in the vessel 1 via the gas introduction tube 3 of coil shape and the connector 4. The air is introduced more then the minimum time required to achieve the equilibrium of concentration in the tube 2 and the sampling for the objective materials is finished, then the tube 2 is removed from the tube 3 and the pipe 6 at the connector 4. Further, by selecting the multi-directional selection cock 7, sampling from respective tube is sequentially enabled and the presence of normal introduction of air can be confirmed by the flow meter 8.
