Fuel oils are frequently contaminated with sodium salts. Users of gas turbines are concerned with the level of sodium in fuel because of the deleterious effects to the turbine. Until recently, on-line continuous methods of analysis did not reliably measure the total sodium in a given fuel. A method is described for the continuous analysis of total sodium present in fuel oils regardless of its chemical form. A small amount of surfactant, “Liquid G” is added to the fuel, and the total sodium in the resulltant solution is determined by flame photometry. The method described provides for the continuous and reliable measurement of sodium in fuel.
