New methods for determining trace amounts of lower chlorinated hydrocarbons （L. C. H. ）in chlorine gas and sodium hypochlorite solution （NaClO soln）were devised. L. C. H. in chlorine gas : After the chlorine gas collected in sampling tube was transferred into 4％NaAsO2 aqueous solution and purified xylene, the volume of chlorine gas was determined through the concentration change of4 ％ NaAsO2, and L. C. H. in 4％ NaAsO2 aqueous solution were measured by means of xylene extraction method. The concentration of L. C. H. in purified xylene was directly measured by ECD-GC. L. C. H. in NaClO soln : The L. C .H. in the NaClO soln quenched with 15w/v％ NaAsO2 were extracted with the purified xylene and were measured by ECD-GC. The determination of L. C. H. was carried out with xylene as internal standard.
