文摘A method for determinaiton of sulfur content at ppb leve in light oils is proposed .The key technique of the method inluces the design of a new of pyrolysis tube,which is charactierized by large capctiy and nested struchture ,and the optimization of operation conditions.The achiveable lowest detection limit is 50ng/g.For the samples in which the sulfur content is less than 1 mg/L,This method features better precision and accuracy,good linearity and quicker test speed.
