Webbdrying step and capable of maintaining a temperature <100 °C (preferably at 80 °C) to prevent sample boiling. e. Convection oven operated at 80 °C (optional) for evaporating samples in a pre-drying step. f. Convection oven operated at 180 ± 2°C for drying samples to a constant weight condition. g. Muffle furnace operated at 550 ± 50 °C. h. WebbEssentially, conductivity is the opposite expression of resistance. The conductivity of a solution is measured between two spatially fixed and chemically inert electrodes. In order to avoid polarization on the electrode surfaces, conductivity measurement is made with an alternating current signal. WebbEA015 Water Total Dissolved Solids (TDS) SM 2540 C, 22nd ed.
