| Abstract: | A new kind of miniature conductivity cell was made with a clever and handy method, which has no dead volume and has large area of electrode, high resolution and sensitivity. Moreover the effect of common-ground and the influence of high voltage on detective system was eliminated effectively. The function of the mini-conductance was also examined. |
