Abstract

The present application discloses a long-term, in-situ sampling and analysis device for sediment pore water and a method thereof. The long-term in-situ sampling and analysis device for sediment pore water includes a bracket, a probe, an elevator, a diverting device, a first water storage device, and a second water storage device, a peristaltic pump, a dissolved gas of sediment pore water analysis device and an in-situ environment measurement device. The present application can collect and store the sediment pore water in an in-situ, long-term and time-phased manner, and in low measuring error level.
