Micro coulomb method is used for determination of sulfur content < 1 ng/μL petroleum products，it is more difficult to get accurate measurement results due to the influence of operating conditions and human factors. TCS - 200 type micro coulomb meter for determination of trace sulfur in heavy hydrogenation cracking naphtha as an example, the various factors on determination of conversion rate and solution were analyzed and discussed to optimize the operating conditions and improve the accuracy of the analysis results.
