Matrix-precipitation for the Determination of Trace Impurities in High-purity Iron

Direct analysis of trace metallic impurities in high purity hydrochloric acid by Agilent 7700s ICP-MS

This application note illustrates the advanced analytical performance and robustness of the Agilent 7700s ICP-MS for the direct determination of metallic impurities in high purity concentrated hydrochloric acid (HCl). The 7700s incorporates a third generation Octopole Reaction System, the ORS3, which effectively removes polyatomic interferences, allowing ultimate detection limits to be achieved...
