Title:
MULTI-SEGMENT SEDIMENT PORE WATER SAMPLER
Document Type and Number:
WIPO Patent Application WO/2012/097528
Kind Code:
A1
Abstract:
A multi-segment sediment pore water sampler is provided at the same axis with several sampling units (1) arranged in a straight line, and each sampling unit (1) is spaced out from each other so that the water body can not be exchanged among each sampling unit (1). The sampler can be used at the same position to collect samples at different depth, which is convenient for sampling the organic pollutant in the sediment pore water body at different depth according to different time resolution. The height of each sampling unit (1) of the sampler is variable and several sampling units (1) have heights different from each other, which is convenient for collector to arrange the heights of the sampling units (1) according to the time resolution required by the actual circumstance of collection spot. The utilization of the sampler is of advantage to improve the time resolution of pollutant water body sampling and the multi-segment sediment pore water sampler can be used in the field of pollutant water body sampling.
