Agilent ICP-MS Journal (November 2011 – Issue 48)

Significance of the Topic

Inductively coupled plasma mass spectrometry (ICP-MS) and complementary atomic spectroscopy techniques are essential for ultra-trace elemental analysis in environmental, pharmaceutical, petrochemical, and industrial applications. Continued innovation is needed to address challenging matrices, improve compliance, and reduce operational costs while maintaining high sensitivity and throughput.

Objectives and Overview

This journal issue highlights six major developments in Agilent’s atomic spectroscopy portfolio:

• MassHunter G7201A software revision for the 7700 Series ICP-MS
• Enhanced methodology for analyzing volatile organic solvents with the 7700 Series
• Introduction of the 4100 MP-AES as a gas-free, microwave plasma AES solution
• Delivery milestone: the 5000th Agilent ICP-MS system in Canada
• Key insights from the inaugural ICP-MS User Group Meeting in Malaysia
• New ICP-MS publications and Agilent’s participation at the 2012 Winter Plasma Conference

Applied Methodology and Instrumentation

The MassHunter G7201A update delivers realtime autotune status visualization, flexible calibration reporting, expanded LC 1200 Infinity control, and full 21 CFR Part 11 compliance via OpenLAB ECM integration. Organic solvent analysis on the Agilent 7700x leverages a frequency-matched RF generator, Peltier-cooled spray chamber, solvent-resistant sample introduction kit, optimized ignition firmware, and a new 1.5 mm ID organics torch. The 4100 MP-AES employs a compressed-air driven, nitrogen-based microwave plasma, eliminating flammable gas supplies and hollow-cathode lamps for cost-effective multi-element emission analysis.

Main Results and Discussion

MassHunter enhancements streamline autotuning, chromatographic data analysis with integrated peak selection and compound tables, and regulatory reporting. The 7700x demonstrates low ng/kg detection limits for V, Ni, As, and Hg in undiluted naphtha, exceptional long-term stability (>1 hour), and reliable plasma ignition with highly volatile solvents. The 4100 MP-AES combines flame-AAS-comparable throughput, sub-ppb detection limits, and broad dynamic range, with simplified installation in remote or regulated labs. The installation of the 5000th ICP-MS underscores global instrument adoption, while user group feedback validated tuning best practices and application robustness.

Benefits and Practical Applications

• Enhanced workflow efficiency: integrated software features reduce method setup and data processing time
• Robust matrix tolerance: direct analysis of organic solvents without dilution or frequent maintenance
• Cost reduction: elimination of flammable gases and consumable lamps in MP-AES
• Regulatory readiness: full electronic records management and compliance support

Future Trends and Potential Applications

Advances in interference-removal technologies (e.g., novel reaction/collision cell gases), data mining with Mass Profiler Professional, and further automation will expand ICP-MS and MP-AES into food authenticity, semiconductor trace analysis, and on-site environmental monitoring. Continued integration with compliance frameworks and cloud-based data management will drive adoption in regulated industries.

Conclusion

The combined hardware, firmware, and software enhancements across Agilent’s ICP-MS and MP-AES platforms deliver significant improvements in sensitivity, robustness, compliance, and cost-efficiency, reinforcing their central role in modern analytical laboratories.
