GB/T 11146-2009 《Crude petroleum - Determination of water - Coulometric Karl Fischer titration method》 Related products

GB/T 11146-2009 stipulates that the Karl Fischer Coulomb Titrimetric method is used to determine the water content of crude oil, which is suitable for all kinds of crude oil samples. This method is based on the quantitative reaction of iodine and water. In the Coulomb Titrator, the water in the sample reacts with the electrolysis solution to produce iodine, and the water content is calculated by the electricity consumed by the electrolysis to produce iodine. The standard specifies the required instruments, such as the Coulomb Titrator, etc., and specifies the preparation of electrolysis solutions and other reagents. Detailed description of Sample Handling steps, including the operation points of sample collection and injection instruments. Standardized titration operation process and data processing. According to this standard, the water content of crude oil can be accurately determined, providing
