Abstract：In order to accurately determine the chlorine content in graphite gaskets, an experimental study on the determination of the chlorine content ion in graphite gaskets was carried out by using elemental analyzer. The chlorine containing gas generated by high temperature combustion of graphite gasket entered the titration cell， and the chlorine content of four different parts of three types of graphite gaskets was determined by microcoulometry. The experiment results show that the chlorine content of different measuring parts of the three types of graphite gaskets was different, the chlorine content of 1# graphite gasket was 200.34 mg/kg, the chlorine content of 2# graphite gasket was 88.64 mg/kg, and the chlorine content of 3# graphite gasket was 408.62 mg/kg. Microcoulomb method has the characteristics of simple operation, fast speed, no loss of sample composition and high precision.
