Abstract Information :
The elemental analysis of distillate products, fuels or the raw materials requires constantly lower detection limits for certain elements. This is to get a better quality with lower concentration of potentially harmful elements but also to ensure a stable production process without damaging effects on catalysts caused by elements like Arsenic, Cadmium, Mercury and others. While traditionally the ICP-AES technique is used for robust, multi-element detection the ICP-MS becomes constantly more accepted as a complementary technique with much lower detection limits for a number of elements. The stable sample introduction and ionization in the inductively coupled plasma is the major challenge accompanied by the interference management. We present a study on the characterization of light Naphtha for Arsenic and Mercury by using the PlasmaQuant MS, ICP-MS. The outstanding performance of the plasma system allows for a direct analysis of organic solvents with detection limits that are an order of magnitude lower compared to ICP-AES. The sample preparation as well as method specific details will be discussed and a comparison with results obtained on ICP-AES will be presented.
