To improve a measurement efficiency and a processing capacity and to improve measurement accuracy by operating a supply device automatically.
A device has a lid 5 that is retained at a combustion pipe 4 airtightly with an O ring and an air lock mechanism 8, at the same time a travel-type table 1 opposite to the combustion pipe 4, further a bridge 9 that can be raised and lowered between the travel-type table 1 and the boat insertion port of the combustion pipe 4, and a wire platinum insertion/removal tool 3 for inserting and removing a boat 2 with a sample into and from the combustion pipe 4 or a reception boat platinum insertion/removal tool. Then, the insertion/ removal of the boat 2 with a weighed sample into and from the combustion pipe of an electrical oven 17 is automated by the control of a computer 19 where procedures for controlling the transportation of the lid opening/closing of the combustion pipe 4 and the wire platinum insertion/removal tool 3, or the reception boat platinum insertion/removal tool, and the boat 2 are programmed.
