ASTM International Chloride in Petroleum Distillates by Microcoulometry ASTM UOP779-92

This method is for determining chloride in liquid hydrocarbons at concentrations ranging from approximately 1 to 1000 ppm. Higher concentrations can be determined with appropriate sample dilution. The method determines the total organic chloride, but some inorganic chloride present as salts is not included. Except for fluoride, other halogens that may be present in the sample are determined as chloride. Both nitrogen and sulfur interfere at concentrations greater than approximately 0.1%.
