In order to establish the rapid method for analyzing carbon, hydrogen and ash in fuel, the improved method have been studied. The analytical procedure is as follows. A sample (200-300mg) on boat is gradually incinerated up to 800°C in helium gas using the newly-devised apparatus. The produced gas is passed through needled copper oxide heated at 800°C and oxidized completely. The atmosphere in the tube is changed from helium gas to pure oxygen gas (the purity is more than 99.99%) and the sample is burned completely, and the occured CO<SUB>2</SUB> and H<SUB>2</SUB>O are absorbed to the absorbers with soda asbestoes or anhydrone res-pectively. Then carbon and hydrogen are determined by means of weighing the increased weight respectively. Also ash is determined by means of weighing the combustion residue. Analytical time is only 17 minutes, and analytical precision is equal to that of JIS method (Liebig method).
