Thermo Fisher iCAP™ PRO ICP-OES Inductively Coupled Plasma Optical Emission Spectrometer

Overview

The Thermo Fisher iCAP™ PRO ICP-OES is a high-performance, vertically oriented inductively coupled plasma optical emission spectrometer engineered for routine and research-grade multi-element trace metal analysis in environmental, clinical, geological, metallurgical, and regulatory compliance laboratories. Operating on the fundamental principle of atomic emission spectroscopy, the instrument atomizes and excites liquid samples in a high-temperature argon plasma (~6,000–10,000 K), causing elemental atoms and ions to emit characteristic photons across the ultraviolet–visible spectrum. These emissions are resolved by a thermally stabilized echelle grating spectrometer with prism cross-dispersion and detected with a high quantum efficiency charge-injection device (CID) array—enabling simultaneous full-spectrum acquisition from 167.021 nm to 852.145 nm with 7 pm spectral resolution at 200 nm. The vertical torch configuration enhances plasma stability for complex matrices—including high-salt, organic, and hydrofluoric acid-containing samples—while minimizing carbon deposition and extending consumable lifetime.

Key Features

• Vertically mounted, semi-demountable EMT torch with corrosion-resistant inner box—optimized for radial and dual-view (radial/axial) observation modes
• Thermally controlled echelle spectrometer with prism cross-dispersion and nitrogen-purged optical path—ensuring long-term wavelength stability and minimal thermal drift
• High-sensitivity CID detector (821 × 512 pixel array) with random-access readout and on-chip background correction
• 27.12 MHz solid-state self-tuning RF generator delivering stable plasma ignition and maintenance across diverse sample matrices
• Three independent mass flow controllers (MFCs) for precise regulation of nebulizer, plasma, and auxiliary gas flows—critical for method reproducibility and inter-laboratory comparability
• Integrated leak-detection interlock system with automatic shutdown upon detection of fluid leakage in the sample introduction pathway
• Three-channel peristaltic pump supporting online internal standard addition, hydride generation, and automated dilution protocols
• Compact benchtop footprint (depth × width × height: 800 × 700 × 650 mm) with low power consumption and reduced argon usage versus legacy systems

Sample Compatibility & Compliance

The iCAP™ PRO ICP-OES accommodates aqueous solutions, digested environmental solids (EPA Methods 200.7, 200.8, 6020B), biological fluids (ISO 17294-2), geological leachates (ASTM D5673), and industrial process streams—including those with up to 25% total dissolved solids (TDS) when paired with optional high-solids introduction kits. It supports full compliance with major regulatory frameworks: US EPA, ISO/IEC 17025, ASTM E1479, and CLSI EP28-A3c for method validation. The system’s hardware and Qtegra™ ISDS software architecture are designed to meet data integrity requirements aligned with FDA 21 CFR Part 11 (electronic records/signatures), EU Annex 11, and GLP/GMP audit trails—including user authentication, electronic signature workflows, and immutable audit logs for all calibration, acquisition, and reprocessing events.

Software & Data Management

Qtegra™ Intelligent Scientific Data Solution (ISDS) provides an integrated, role-based platform for method development, real-time spectral visualization, automated interference correction (e.g., spectral overlap, background drift), and multi-level reporting. Its intuitive interface enables concurrent tasks: adding wavelengths during acquisition, applying matrix-matched or standard-addition quantitation, generating QC charts (Levey-Jennings, Shewhart), and exporting results to LIMS via ASTM E1384 or HL7-compliant formats. All raw spectral data are stored in vendor-neutral .qgd format, ensuring long-term archival accessibility. Software validation packages—including IQ/OQ documentation templates and risk-based UAT checklists—are available to support laboratory accreditation readiness.

Applications

The iCAP™ PRO ICP-OES delivers robust performance in high-throughput trace element quantification across diverse sectors: monitoring heavy metals (As, Cd, Pb, Hg) in drinking water per WHO and EU Directive 2020/2184; speciation-supporting analysis of nutrient cations (Ca, Mg, K, Na) and toxic elements in food and feed (AOAC 2015.03); rapid screening of rare earth elements (REEs) in battery-grade cathode materials; elemental impurity testing in pharmaceutical excipients per ICH Q3D; and isotopic ratio-ready analysis of Li, B, Sr in geochemical fingerprinting studies. Its dual-view capability allows method-switching without hardware reconfiguration—enabling both high-sensitivity axial mode for sub-ppt detection and robust radial mode for high-TDS samples.

FAQ

What is the certified wavelength range and resolution specification?
The instrument covers 167.021–852.145 nm with ≤7 pm spectral resolution measured at 200 nm under standard operating conditions.
Is the system compliant with FDA 21 CFR Part 11 requirements?
Yes—Qtegra™ ISDS supports electronic signatures, audit trail logging, user access controls, and data integrity features validated for regulated environments.
Can the iCAP™ PRO handle high-salt or organic solvent samples?
It is optimized for aqueous matrices but supports up to 25% TDS with optional high-solids nebulization and can accommodate up to 20% methanol or ethanol with appropriate plasma stabilization and cooling gas adjustments.
What consumables require regular replacement and typical service intervals?
Nebulizer tips (every 3–6 months), spray chamber O-rings (6–12 months), torch center tubes (12–24 months), and CID detector vacuum pump oil (annually)—all tracked via Qtegra™ maintenance scheduler.
Does the ACT label apply to the entire instrument or only specific components?
The ACT (Accountability, Consistency, Transparency) Environmental Impact Label applies to the complete iCAP™ PRO system—including manufacturing energy use, packaging recyclability, end-of-life material recovery rate, and operational carbon footprint per analysis cycle—as verified by My Green Lab.
