Abstract

An elemental analysis device includes a heating furnace in which a test sample that is placed in a crucible is heated so that a sample gas is generated from the test sample, an inflow path through which a carrier gas is introduced into the heating furnace, an outflow path through which a mixture gas made up of the carrier gas and the sample gas is led out from the heating furnace, a dust filter that is provided on the outflow path, an analysis mechanism that is provided on the outflow path on a downstream side from the dust filter, and that detects one or a plurality of predetermined components contained in the mixture gas, and a cleaning gas supply mechanism that supplies cleaning gas to the dust filter in an opposite direction from a direction in which the mixture gas is flowing.
