摘　　要：利用LC－2000通用微机库仑仪测定出矿原油中总氯含量，通用微机库仑仪检测的最优条件为：汽化段温度750℃、燃烧段温度900℃、稳定段温度750℃；氧气流量300 mL／min、氮气流量120 mL／min。该方法测量标准样值与真值相对误差低于0．5％；样品测量重复性相对误差0．39％～3．75％，具有较好的测量重复性和准确性。The total chlorine content in crude oil was determined by LC-2000 microcoulometer.The optimal vaporization temperature for the microcoulometer was 750 ℃, and the optimal combustion temperature and stable temperature was 900 ℃ and 750 ℃ respectively with oxygen and Nitrogen flow rate of 300 mL/min and 120 mL/min.The relative error of measurement results between standard sample value and true value was less than 0.5%, and the repeatability error range was 0.39% ~3.75% which showed high reliability of the measurement results.
