Overview
Flat double-sided DGT $r $n (1) can simultaneously determine 15 rare earth elements (CH3Hg+, Hg2+); amp; amp; amp; amp; amp; amp; S (- II) 2D amp; amp; amp; amp; amp; amp; 16 types of cations and anions synchronized (P, As, Cr, Mo, Sb, Se, V, W, Fe, Cd, Co, Cu, Mn, Ni, Pb, Zn); $r $n (2) Multi index synchronous measurement; $r $n (3) in-situ sampling and monitoring, with minimal damage to the native environment; $r $n (4) has high measurement capacity and strong environmental resistance.
Product Details
Flat panel double-sided DGT film diffusion gradient in-situ sampling equipment
1Composition and Structure
Flat double-sided DGTThe shell is shown in the following figure. A in the picture、BFor the two basic components of the flat structure, ATo place the bottom plate of the film for placing three layers of film, BAs a cover plate, it serves to fix the three-layer film and seal the outer edge of the bottom plate. After fixing, A、BComposition of tablet device CThe length of the exposed window is 150mmWidth 20mmThe target ion enters DGT through the exposure windowDiffusion layer.
TCH-95&ZrO-CA DGTproduct structure
DGTThe longitudinal structure of the bottom of the shell allows the exposed surface of the device to be in two planes from the bottom *, with the bottom forming a triangleThis structure canReduce the destructive effect of device insertion on sediment interfaces, whileDGTThe exposed surface is in contact with the sediment, reducing the interference of overlying underwater irrigation on the measurement.
