Applications
Analysis of Waters by ICP-QQQ with a Dual-Cell System and Discrete Sampling
This application note shows how the Agilent 9500 ICP-QQQ with Dual-Cell System in Advanced Helium Mode and AVS MS discrete sampling enables fast, accurate analysis of environmental waters. In a two-hour sequence, 141 samples and QCs were measured in 138 minutes, delivering 50% higher throughput than a comparable single-quad ICP-MS method while maintaining accuracy, stability, and robust performance for high-matrix samples.
Automated Analysis of Foods by ICP-QQQ with Discrete Sampling and Autodilution
This application note shows how the Agilent 9500 ICP-QQQ with Dual-Cell System, AVS MS discrete sampling, and ADS 2 autodilution delivers fast, accurate, AOAC-compliant food analysis. The workflow automates calibration and dilution, removes challenging interferences on As and Se, and improves productivity with analysis times about 30 seconds faster per sample than comparable single-quad ICP-MS methods, while maintaining robust long-term stability.
Direct Analysis of Seawater Using ICP-QQQ and Integrated Advanced Valve System
This application note shows how the Agilent 9500 ICP-QQQ with AVS MS enables direct seawater analysis using online reverse dilution. The robust method achieved ppt-level MDLs for 26 elements, 90–110% recoveries for CRMs and spiked samples, and stable performance over 100 undiluted seawater injections, meeting EPA Method 200.8 QC requirements while simplifying sample prep and supporting high-throughput analysis of heavy matrix samples.
Agilent 9500 ICP-QQQ with m-Lens for Ultratrace Analysis of High-Purity Reagents
This application note shows how the Agilent 9500 ICP-QQQ with optional m-lens delivers ultratrace analysis of high-purity reagents under hot-plasma conditions. Using preset methods for 1% HNO3 and 9.8% H2SO4, the system achieved sub- or single-digit ppt detection limits and low backgrounds across target analytes, including challenging Zn in H2SO4, providing a sensitive, reproducible workflow for semiconductor-grade impurity analysis.
