Water, as an electrolyte, is an intrinsic part of any corrosion cell. It is well known that the chemistry of an electrolyte has a profound influence on the rates of corrosion, and the corrosion mechanisms that may take place. Rysco Corrosion Services performs onsite measurements at the time of sampling (pH, temperature, and dissolved gases) to ensure the accuracy of the water chemistry results. Results include total alkalinity, bicarbonate and carbonate, chloride, bromide and iodide, sulphate, pH and specific gravity, boron, barium, calcium, magnesium, potassium, sodium, strontium, iron and manganese. Calculations are performed for ion balance, total dissolved solids, and scaling indices, and the report includes a scaling tendencies plot.
