Studies on the Errors, in the Microdetermination of Carbon and Hydrogen, due to the Positions of Sample.

탄수원소분석에 있어서 검체충전위치에 기인하는 오차에 대한 연구

To reduce the errors, in the microdetermination of carbon and hydrogen, by the electrical automatic combustion apparatus, measured the errors due to the positions of sample in the carbon and hydrogen combustion tube. The samples used are glucose, acetanilide, phenacetin and diazoaminobenzene. Experimented positions of samples were 3cm, 5cm, 7cm, and 9cm from the front edge of the long stationary burner. In this experiment, it was found that the most suitable position of sample in the carbon and hydrogen combustion tube is 8cm from the long stationary burner.
