Environment Dissolved Solute Sampling Across an Oxic-Anoxic Soil-Water Interface Using Microdialysis Profilers Sha Zhang1,2, Zhaofeng Yuan2, Yujia Cai2, Hao Liu2, Ziyan Liu2, Zheng Chen2 1Department of Geography and Planning, University of Liverpool, 2Department of Health and Environmental Sciences, Xi’an Jiaotong-Liverpool University A microdialysis profiler is described to sample dissolved porewater solutes across an oxic-anoxic soil-water interface in situ with minimal disturbance. This device is designed to capture rapid changes in concentration-depth profiles induced by disturbances at the soil-water interface and beyond.
