Determination of impurities in high-purity mullite and alumina by ICP-AES.

Direct Analysis of Trace Metallic Impurities in High Purity Hydrochloric Acid by 7700s/7900 ICP-MS

This application note illustrates the advanced analytical performance and robustness of the Agilent 7700s/7900 ICP-MS for the direct determination of metallic impurities in high purity concentrated hydrochloric acid (HCl). The 7700s/7900 incorporates an Octopole Reaction System (ORS), which effectively removes polyatomic interferences, allowing ultimate detection limits to be achieved for eleme...

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...

Analysis of Trace Metal Impurities in High Purity Hydrochloric Acid Using ICP-QQQ

Determination of Trace Elements in High-Purity Molybdenum by Solid-Phase Extraction/ICP-MS

We attempted a simple pretreating method consisting of solid-phase extraction using bonded silica gel with benzenesulfonic acid (SCX) as the solid-phase sorbent to determine trace elements in pure molybdenum samples by means of inductively coupled plasma mass spectrometry (ICP-MS). Molybdenum was anionized by adding hydrogen peroxide solution to a sample decomposed with acid, and separated from...
