元素分析装置
Document Type and Number:
Japanese Patent JP7445743
Kind Code:
B2
Abstract:
In order to provide an elemental analysis device that enables the dust filter replacement frequency to be reduced, and enables the time and labor required for maintenance performed by a user to also be reduced, there is provided an elemental analysis device that includes a heating furnace 3 in which a test sample that is placed in a crucible MP is heated so that a sample gas is generated from the test sample, an inflow path L1 through which a carrier gas is introduced into the heating furnace 3, an outflow path L2 through which a mixture gas made up of the carrier gas and the sample gas is led out from the heating furnace 3, a dust filter 4 that is provided on the outflow path L2, an analysis mechanism AM that is provided on the outflow path L2 on a downstream side from the dust filter 4, and that detects one or a plurality of predetermined components contained in the mixture gas, and a cleaning gas supply mechanism R that supplies cleaning gas to the dust filter 4 in an opposite direction from a direction in which the mixture gas is flowing.
