Thermo Fisher iCAP 7000 Used ICP-OES Spectrometer

Overview

The Thermo Fisher iCAP 7000 is a high-performance, second-hand inductively coupled plasma optical emission spectrometer (ICP-OES) engineered for robust, multi-element trace metal analysis in demanding laboratory environments. Based on the fundamental principle of atomic emission spectroscopy, the instrument excites analyte atoms and ions in a high-temperature argon plasma (~6,000–10,000 K), then measures element-specific emission lines across the UV-Vis spectral range (130–800 nm) using a high-resolution simultaneous optical system. Its dual-view capability—supporting both radial and axial plasma observation—enables flexible method optimization: radial mode delivers enhanced matrix tolerance for complex samples (e.g., wastewater, digested soils), while axial mode provides sub-part-per-trillion detection sensitivity for ultra-trace applications. The solid-state 27.12 MHz RF generator ensures stable plasma ignition and low power consumption, while the thermally regulated monochromator and precision wavelength calibration maintain long-term photometric stability—critical for regulatory-compliant batch analysis over extended periods.

Key Features

• Charge Injection Device (CID) detector with full-frame readout, enabling wide linear dynamic range (>10⁶) and resistance to signal saturation during high-concentration analysis.
• Enhanced Matrix Tolerance (EMT) plasma torch design reduces polyatomic interferences and minimizes sample dilution requirements—particularly beneficial for high-salt or organic-rich matrices.
• Modular sample introduction system with auto-connect gas manifolds and tool-free nebulizer/spray chamber interchangeability, reducing setup time and cross-contamination risk.
• Integrated solid-state RF generator with real-time impedance matching and adaptive power regulation—improving plasma stability during variable sample uptake or solvent changes.
• Automated plasma tuning and wavelength calibration routines executed via Qtegra ISDS, ensuring consistent analytical performance across operator shifts and instrument relocations.
• Thermally stabilized optical bench with active temperature control (±0.05 °C), minimizing thermal drift and preserving spectral resolution over multi-hour analytical runs.

Sample Compatibility & Compliance

The iCAP 7000 accommodates aqueous solutions, acid-digested environmental and biological samples, diluted industrial effluents, and laser ablation-generated aerosols (when paired with compatible LA systems). Its hardware architecture and software validation framework support compliance with internationally recognized standards including ASTM D5185 (metals in lubricating oils), ISO 11885 (water quality), USP Chapters <232> and <233> (elemental impurities in pharmaceuticals), and EPA Methods 200.7 and 6010D (drinking water and solid waste). All refurbished units undergo functional verification per Thermo Fisher’s used-instrument refurbishment protocol, including detector dark current assessment, plasma stability testing under load, and spectral line intensity reproducibility checks (RSD ≤ 1.5% over 10 replicates).

Software & Data Management

Qtegra ISDS serves as the validated data acquisition and processing platform, designed to meet GLP and GMP requirements. It supports full audit trail functionality compliant with FDA 21 CFR Part 11—including electronic signatures, user access levels, and immutable record retention. Method templates are pre-optimized for common matrices (e.g., soil extracts, pharmaceutical excipients, petrochemicals), significantly reducing development time. Advanced tools include interference correction algorithms (e.g., internal standardization, background correction at multiple points), automated QC flagging (e.g., drift alerts, calibration failure notifications), and customizable report generation aligned with LIMS export formats (ASTM E1461, HL7). Data integrity is reinforced through encrypted local storage and optional networked backup configurations.

Applications

The iCAP 7000 is routinely deployed in environmental monitoring laboratories for routine analysis of As, Cd, Cr, Pb, and Hg in drinking water and leachates; in contract testing labs performing USP-compliant elemental impurity screening of drug substances; in mining and metallurgy QA/QC for rapid assay of base metals and rare earth elements in ores and concentrates; and in academic research settings requiring high-throughput, multi-isotope trace profiling in geological or biological specimens. Its dual-view flexibility and EMT torch make it especially suitable for direct analysis of high-TDS samples without extensive offline dilution—reducing consumable costs and analyst exposure time.

FAQ

What is the typical detection limit performance for this refurbished unit?
Sub-ppb detection limits (e.g., 0.003 µg/L for Mn at 257.610 nm, axial view) are achievable under optimal operating conditions and verified during post-refurbishment performance qualification.
Is the instrument supplied with original Thermo Fisher documentation and calibration records?
Yes—each unit includes a complete set of factory service logs, final PQ report, and a Certificate of Refurbishment detailing all replaced components and functional test results.
Can the iCAP 7000 be integrated into an existing LIMS environment?
Yes—Qtegra ISDS supports ODBC-compliant data export, ASTM E1461-compliant file transfer, and configurable API endpoints for bidirectional LIMS communication.
What maintenance is required during the 6-month warranty period?
Routine maintenance includes weekly torch cleaning, monthly nebulizer inspection, and quarterly RF matching network verification—all documented in the included Thermo Fisher Preventive Maintenance Guide.
Are consumables (tubes, nebulizers, torches) included with the system?
A starter kit containing one EMT torch, two glass concentric nebulizers, one Scott-type spray chamber, and associated O-rings and fittings is provided with each unit.
