Abstract:
Objective To investigate the quality control of blind sample test on chlorinated organic compounds in activated carbon tube.
Methods Blind samples containing tetrachloroethylene, carbon tetrachloride and trichloroethylene in activated carbon tubes were analyzed by using CS2 solvent desorption and gas chromatography.
Results The examination of three chlorinated organic compounds in activated carbon tube was satisfactory.
Conclusions Quality control of blind sample test was important to promote and determine the ability and management level of a laboratory.
