Analysis of cations in precipitation
In the process of purifying the air, rainfall also dissolves ions in aerosol pollutants, so it is meaningful to analyze cations in precipitation.
This solution adopts the dynamic range conductivity detector produced by Qingdao Reepo Analytical Instrument Co., Ltd. Its advantages are that there is no need to set the range, no need to adjust the zero, and the linear range is long. Under the premise that the column capacity allows, the sample can be injected directly. Detect high and low concentration ions.
The signal unit of the detector is μS, not mV.
