<p>An apparatus for supplying gases of those substance which are liquid or solid at room temperature comprising a gas supplying apparatus comprising a container (12) for receiving a substance (11) which is liquid or solid, a means for heating the container, an inlet pipe (13) connected to the container (12) in order to introduce a carrier gas into the container, a carrier gas line (15) for supplying the carrier gas to the inlet pipe (13), an outlet pipe (14) connected to the container (12) in order to introduce the vaporized gas of the substance (11) out of the container (12), and a substance gas line (40) connected to the outlet pipe (14), wherein the substance (11) received in the container (12) is vaporized by heating and the vaporized gas thus generated is associated with the carrier gas and supplied through the substance gas line (40), characterized in that a vacuum oven (30) in which the container (12), the inlet pipe (13), the outlet pipe (14), and a part of the carrier gas line (15) and a part of the substance gas line (40) are housed therein is used as the means for heating the container (12) and that said vacuum oven (30) is purged with a chemically inactive gas to fill it with inert atmosphere.</p> |
