Total Fixed Solids

What Does Total Fixed Solids Mean?

Total fixed solids refer to the sum of suspended solids and dissolved solids in a given mixture that contains both a liquid and an insoluble phase component. The total fixed solid is often inversely proportional to the rate of corrosion occurrence of a metallic substrate that is exposed to a given phase mixture environment.

Corrosionpedia Explains Total Fixed Solids

The total fixed solids of a mixture can be empirically obtained by separating the solid and liquid phase components by evaporation. The non-evaporated component that remains may then be weighed to give a mass measurement in grams.

Insoluble components in a mixture are often salts, which include carbonates, sulfates and phosphate. These salts present ions that have a direct impact on the pH of the water or atmospheric environment in which a metallic surface or equipment may be located. This variation in pH may create an increasingly corrosive environment due to variations in acidity. Such variation can be measured via a sample collection of components such as carbon dioxide, carbonic acid, bicarbonate and carbonate.
