AB  - Rapid and sensitive monitoring of volatile organic compounds (VOCs) in aqueous 
      samples is very important to human health and environmental protection. In this 
      study, an on-line spray inlet proton transfer reaction mass spectrometry 
      (SI-PTR-MS) method was developed for the rapid and sensitive monitoring of 6 
      different kinds of VOCs, namely acetonitrile, acetaldehyde, ethanol, acetone, 
      aether, and methylbenzene, in aqueous samples. The response time, limit of 
      detection (LOD), and repeatability of the SI-PTR-MS system were evaluated. The 
      response of the SI-PTR-MS was quite rapid with response times of 31-88 s. The 
      LODs for all these VOCs were below 10 mug/L. The LOD of methylbenzene was 
      0.9 mug/L, much lower than the maximum contaminant level (MCL) in drinking water. 
      The repeatability of this method was evaluated with 5 replicate determinations. 
      The relative standard deviations (RSDs) were in the range of 0.8-3.1%, indicating 
      good repeatability. To evaluate the matrix effects, the SI-PTR-MS system was 
      employed for on-line monitoring of these 6 VOCs in different aqueous matrices, 
      including lake water, tap water, and waste water. The relative recoveries were in 
      the range of 94.6-106.0% for the lake water, 96.3-105.6% for the tap water, and 
      95.6-102.9% for the waste water. The results indicate that the SI-PTR-MS method 
      has important application values in the rapid and sensitive monitoring of VOCs in 
      these aqueous samples. In addition, the effect of salt concentration on the 
      extracting efficiency was evaluated. The results showed that the LOD of the 
      SI-PTR-MS could be further decreased by changing the salt concentration.
