Abstract:
Trace metals in gasoline are not only a major source of environmental pollution they can also cause automotive engine failures. ICP-OES is often used for the elemental analysis in petroleum products due to its reliability, robustness, and sensitivity. However, high volatility of gasoline can affect the stability of signal and lead to carbon build up on the torch that may cause the plasma to extinguish. A programmable temperature-controlled spray chamber (IsoMist) was used to reduce vapor loading of gasoline and oxygen was added to reduce carbon build up in the torch injector, maintaining a stable plasma and a clean sample introduction system.
