Overview
The sediment sampler flat single-sided DGT: TCH DGT flat DGT shell is shown in the following figure. In the figure, A and B are two basic components of a flat plate structure. A is the bottom plate for placing the membrane, used to place the three-layer membrane, and B is the cover plate, which plays a role in fixing the three-layer membrane and sealing the outer edge of the bottom plate. After fixing, A and B form a flat plate device C. The length of the exposed window is 150mm and the width is 20mm. The target ions enter the DGT diffusion layer through the exposed window.
