Objectives and Study Overview

This application note presents the Thermo Scientific iCAP RQplus ICP-MS, designed to simplify complex sample workflows while delivering stable and accurate trace element results. The note reviews system capabilities, software integration, performance metrics, and suitability across various industries.

Methodology and Used Instrumentation

The iCAP RQplus ICP-MS combines optimized sample introduction hardware with active performance monitoring. Key components include:

• Argon Gas Dilution (AGD) modes (low, medium, high) with preset dilution factors for direct analysis of diverse matrices
• Qtegra ISDS Software for workflow-structured method creation, data acquisition and QA/QC automation
• EasyClick Compact peristaltic pump ensuring consistent sample uptake
• Quick-connect torch and injector assembly for rapid maintenance
• QCell collision/reaction cell with helium gas and kinetic energy discrimination to suppress polyatomic interferences
• Thermo Scientific iSC-65 Autosampler and Hawk consumables monitoring

Main Results and Discussion

Performance evaluation demonstrated:

1. Stable calibration over multiple days with recoveries within specification (e.g., arsenic and other elements over three days)
2. Minimal carryover across high matrix samples due to automated rinse and AGD modes
3. Robust internal standard signals during prolonged organic solvent analysis (acetonitrile over 28 hours)
4. Automated daily performance checks via one-click Get Ready reducing setup time and avoiding drift

These features ensure consistent accuracy and productivity for high-throughput elemental labs.
