Simultaneous ICP Atomic Emission Spectrometers ICPE-9800 Series

Importance of the Topic

The simultaneous ICP atomic emission spectrometry (ICP-AES) is a cornerstone technique for multi-elemental analysis across diverse sectors, including environmental monitoring, food safety, pharmaceuticals, petrochemicals, and metal/electronics production. Its high throughput, wide dynamic range, and ability to handle complex matrices make it indispensable for ensuring regulatory compliance, product quality, and consumer safety.

Objectives and Overview of the Article

This article presents an expert summary of the Shimadzu ICPE-9800 Series of simultaneous ICP-AES spectrometers, highlighting their next-generation design, enhanced performance features, cost-saving measures, and user-oriented software. It reviews how these systems address analytical challenges such as trace-level detection, matrix interference, and operating cost reduction.

Methodology and Analytical Setup

The ICPE-9800 Series employs dual axial and radial viewing to cover a dynamic concentration range from parts-per-billion (ppb) to percentage levels in a single run. A large, back-illuminated 1-inch CCD detector captures all wavelengths simultaneously as an image, enabling post-analysis wavelength selection and reanalysis without additional sample runs. The vertically oriented torch minimizes memory effects and supports direct introduction of aqueous, high-salt, and organic solvent samples without auxiliary oxygen. Key innovations such as Eco mode, Mini-torch, and a vacuum spectrometer halve argon consumption and shorten startup/shutdown times.

Used Instrumentation

• ICPE-9810 Axial ICP-AES and ICPE-9820 Dual Axial/Radial ICP-AES systems
• Back-illuminated CCD spectrometer with Schmidt aberration correction
• Vertical plasma torch with cooling jacket and interchangeable orifice units
• Eco mode control for standby gas reduction
• Mini-torch for high excitation efficiency
• Vacuum spectrometer for VUV region without purge gas
• Optional accessories: ultrasonic nebulizer, hydride generator, autosamplers, peristaltic pump

Main Results and Discussion

Performance evaluations demonstrate:

• A broad linear dynamic range from ppb to percent concentrations by switching views, improving throughput and eliminating sample dilution steps.
• Sensitivity enhancements of up to 10× with ultrasonic nebulization and hydride generation for trace elements like As, Se, and Hg.
• Significant reduction in memory effects for boron and other elements through vertical torch orientation, cutting rinse times by over 50%.
• Stable continuous operation over 3–9 hours with relative concentration drift below 5% for multiple elements.
• Operational cost savings of more than 50% on argon gas through Eco mode, Mini-torch, and vacuum design, translating into ~USD 25 000–45 000 saved over three years under typical usage scenarios.

Benefits and Practical Applications of the Method

• Food Safety and Nutrition: Simultaneous quantification of toxic trace metals and essential minerals across wide concentration ranges to comply with labeling and hazard regulations.
• Environmental Monitoring: Robust analysis of drinking water and wastewater with high sensitivity, minimal clogging, and rapid rinse cycles for high throughput.
• Pharmaceutical QA/QC: Compliance with ICH Q3D elemental impurity guidelines using a 1-inch CCD detector to meet strict detection limits without oxygen support for organic solvents.
• Chemical and Petrochemical Control: Reliable analysis of high-salt and organic samples through interchangeable torches and chambers, supported by intuitive ICPEsolution software.
• Metals and Electronics: Accurate measurement of complex matrices with comprehensive spectral databases, automatic interference correction, and long-term stability for quality control.

Future Trends and Opportunities for Use

Advances in automation, cloud-based data management, and AI-driven method development are poised to further streamline ICP-AES workflows. Integration with electronic laboratory notebooks, remote operation via web terminals, and expansion into ultra-trace VUV spectroscopy will broaden applications in nano-materials, clinical diagnostics, and pharmaceutical research. Ongoing improvements in detector technology and sample introduction promise even lower detection limits and higher throughput.

Conclusion

The Shimadzu ICPE-9800 Series represents a significant evolution in simultaneous ICP-AES, combining axial/radial dual views, a million-pixel CCD, and cost-reducing features to deliver unparalleled performance, robustness, and operational economy. Its versatile design and user-friendly software make it an ideal choice for demanding analytical laboratories aiming to maximize throughput, accuracy, and regulatory compliance.
