Shimadzu ICPS-7000 Microwave-Induced Plasma Optical Emission Spectrometer (Used, Refurbished)

Overview

The Shimadzu ICPS-7000 is a high-performance microwave-induced plasma optical emission spectrometer (MIP-OES) engineered for precise, multi-element quantitative analysis of metals and some non-metals in liquid matrices. Unlike conventional inductively coupled plasma (ICP) systems that rely on argon-fed RF torches, the ICPS-7000 utilizes a compact, low-power 2.45 GHz microwave plasma source operating at atmospheric pressure—enabling stable excitation of analytes with reduced operational gas consumption and lower thermal load on optical components. This architecture delivers sub-ppb (ng/L) detection limits for over 60 elements—including As, Cd, Pb, Hg, Se, Cr, and U—while maintaining robust resistance to matrix interferences from complex samples such as saline waters, digested biological tissues, and acid-leached geological materials. Its fixed-grating echelle optical system, coupled with a high-sensitivity CCD detector, provides simultaneous spectral acquisition across 167–800 nm with effective resolution better than 0.007 nm (FWHM), supporting both qualitative identification and high-precision quantification without wavelength scanning.

Key Features

• Microwave plasma source (2.45 GHz, ~1 kW input power) with automatic impedance matching and real-time plasma monitoring for exceptional long-term stability (RSD < 1.5% over 4-hour operation)
• Echelle spectrograph with prism-crossed grating design and thermoelectrically cooled, back-thinned CCD detector (1024 × 1024 pixels) for high quantum efficiency in UV-VIS-NIR range
• Integrated peristaltic pump and dual-channel nebulizer system compatible with aqueous (HCl/HNO₃/HF media) and organic solvents (e.g., MIBK, xylene) without hardware modification
• Dual gas control module managing Ar (plasma support) and O₂ (for carbon-rich sample introduction), with mass flow controllers calibrated to ±0.5% full scale
• Modular RF generator, optical bench, and sample introduction unit—all factory-aligned and verified during refurbishment to original Shimadzu performance specifications
• Compliance-ready architecture: audit trail logging, electronic signatures, and data integrity safeguards aligned with FDA 21 CFR Part 11 and GLP/GMP documentation standards when operated with validated LabSolutions ICP software

Sample Compatibility & Compliance

The ICPS-7000 accepts liquid samples introduced via concentric glass or quartz nebulizers, with optional micro-flow and ultrasonic nebulization modules available for enhanced sensitivity. It routinely analyzes environmental water (drinking, wastewater, seawater), pharmaceutical excipients, semiconductor-grade reagents, food extracts, and metallurgical digests. All critical optical and plasma components undergo post-refurbishment verification against Shimadzu’s internal calibration protocols (QAP-ICP-003 Rev. D), including wavelength accuracy ( 0.9999 over 5 orders of magnitude), and background equivalent concentration (BEC) validation per ISO 11885. The system meets essential requirements for ISO/IEC 17025 accredited laboratories performing elemental testing under EPA, ASTM, and pharmacopeial methods.

Software & Data Management

Operation is fully supported by Shimadzu LabSolutions ICP software (v2.8x or later), which provides method development wizards, multi-point calibration with internal standard correction, spectral interference diagnostics, and automated QC checks (blanks, duplicates, CRMs). Raw spectral data are stored in vendor-neutral .spc format; processed results export to CSV, PDF, and LIMS-compatible XML. Audit trails record all user actions—including method edits, integration parameter changes, and result approvals—with time-stamped, immutable entries. Optional 21 CFR Part 11 compliance packages include role-based access control, electronic signature workflows, and encrypted database backups.

Applications

• Environmental monitoring: Quantification of regulated metals in surface water, groundwater, and wastewater per EPA Methods 200.7 and 200.8
• Pharmaceutical quality control: Trace metal screening in APIs and excipients per USP and
• Geochemical analysis: Multi-element profiling of soil and sediment digests using HF/HNO₃/HClO₄ digestion protocols
• Food safety: Detection of toxic elements (As, Cd, Pb) in infant formula, cereals, and seafood per EU Commission Regulation (EU) No 1881/2006
• Materials science: Impurity profiling in high-purity silicon, lithium battery cathode precursors, and catalyst supports

FAQ
