Abstract
The present invention discloses a multi-section sediment pore water sampler, which comprises a plurality of sampling units arranged coaxially and separated with each other; this arrangement ensures no water exchange occurred between two adjacent sampling units, collection of the sediment pore water samples from different depths of a same position is realized, whereby to facilitate organic pollutant sampling in sediment pore water at different depths according to different time resolutions. Furthermore, as the heights of the sampling units as well as the clearances between two neighboring sampling units may be various, in use users can configure the sampler according to the actual condition of the time resolution required, thus this sampler can also help improve the time resolution of water sampling.
