AB  - An analytical technique of in-line coupling headspace liquid-phase 
      microextraction (HS-LPME) with capillary electrophoresis (CE) was proposed to 
      determine volatile analytes. A special cover unit of the sample vial was adopted 
      in the coupling method. To evaluate the proposed method, phenols were used as 
      model analytes. The parameters affecting the extraction efficiency were 
      investigated, including the configuration of acceptor phase, kind and 
      concentration of acceptor solution, extraction temperature and time, salt-out 
      effect, sample volume, etc. The optimal enrichment factors of HS-LPME were 
      obtained with the sample volume of about half of sample vials, which were 
      confirmed by both the theoretical prediction and experimental results. The 
      enrichment factors were obtained from 520 to 1270. The limits of detection (LODs, 
      S/N=3) were in the range from 0.5 to 1 ng/mL each phenol. The recoveries were 
      from 87.2% to 92.7% and the relative standard deviations (RSDs) were lower than 
      5.7% (n=6). The proposed method was successfully applied to the quantitative 
      analysis of the phenols in tap water, and proved to be a simple, convenient and 
      reliable sample preconcentration and determination method for volatile analytes 
      in water samples.
