The new Agilent 7500cx allows the user to achieve the full potential of ICP-MS for semiquantitative elemental screening of a wide range of sample types. Complex, unknown samples can be analyzed with better speed, accuracy, and data integrity than ever before, since all matrix interferences are removed in the Octopole Reaction System (ORS) using helium collision mode. Results are presented for three different certified reference materials.
The document details how the Agilent 7500cx Inductively Coupled Plasma Mass Spectrometer (ICP-MS) enables faster, simpler, and more accurate semiquantitative analysis. It highlights the unique capability of the Octopole Reaction System (ORS) to eliminate polyatomic interferences using Helium collision mode with Kinetic Energy Discrimination (KED). This allows for a single set of acquisition conditions across all analytes, overcoming limitations found in other Collision/Reaction Cell instruments.
| RF power | 1550 W |

It allows all elements to be acquired under a single, universal set of CRC conditions by eliminating polyatomic interferences.
The semiquantitative results were within + 40% of the certified concentration.
