The sulfur contents in coal tar samples under different temperatures are determined.The results showed that the average value of the sulfur content increases with rising temperature,with maximum standard deviation 0.002 29% and maximum coefficient of variation 0.559%.The precisions of the samples measured under different temperatures,however,remain consistent.It is suggested that the sample temperature should be relatively kept constant to minimize the impact of the sample temperature variation on the determination results of the sulfur content.
