TI  - Time-weighted average water sampling with a diffusion-based solid-phase 
      microextraction device.

AB  - A new diffusion-based solid-phase microextraction (SPME) time-weighted average 
      (TWA) field water sampling device was developed and investigated by field trial. 
      The sampler is constructed with copper tube and caps and a commercial SPME fiber 
      assembly. The device possesses all advantages of SPME; it is solvent-free, 
      reusable, combines sampling, isolation and enrichment into one step, and the 
      fiber can be directly injected into a gas chromatograph for analysis with a 
      commercial SPME fiber holder, without further treatment. Field trials in Laurel 
      Creek (Waterloo, Ont., Canada) and Hamilton Harbour (Hamilton, Ont., Canada) 
      illustrated that the device is durable, easy to deploy, and the mass uptake of 
      the device is independent of the face velocity. The device provides good 
      precision [relative standard deviations (RSDs) are less than 20%] and the data 
      obtained with this device are quite comparable to those obtained with the spot 
      sampling method, which demonstrates that the newly developed SPME water sampling 
      device is suitable for long-term monitoring of organic pollutants in water.
