This document demonstrates the effective interference removal of a range of elements in a challenging and complex sample matrix using the Agilent 7500ce ICP-MS with a single set of He cell gas conditions, highlighting its high performance.
The document presents an application demonstrating that the Agilent 7500ce Inductively Coupled Plasma Mass Spectrometer (ICP-MS) can utilize a single set of Helium cell gas conditions to provide effective interference removal for various elements in complex sample matrices. It highlights the advantages of Kinetic Energy Discrimination (KED) over traditional reactive gas modes.
It removes all polyatomic species based on their size rather than their relative reactivity with a reaction gas.
5.5 mL/min of Helium gas only was added to the cell.
The energy of all ions entering the cell must be very tightly controlled.
