2002 ICPPC Cl Si in Gasoline - Technical Note

This technical note demonstrates the ability of the Teledyne Leeman Labs Prodigy Plus ICP-OES system to determine various elements in gasoline. The presence of certain elements in gasoline can have an adverse impact on internal combustion engines. Ionic and organic forms of chlorine (Cl) are corrosive for many metals. Silicon (Si) contamination can cause O2 sensors to give false rich signals, resulting in the engine running lean. The concentration limit for Cl and Si in gasoline is 1 mg/L per the National Technical Committee for Standardization of Petroleum Products and Lubricants GB/T 33647-2017.
