Overview
The Agilent 7800 ICP-MS is a high-sensitivity, quadrupole-based inductively coupled plasma mass spectrometer engineered for trace elemental analysis at sub-femtogram-per-gram detection levels. Operating on the principle of ionization in a high-temperature Ar plasma (~7,000 K), followed by mass separation via a robust RF-only quadrupole mass filter and detection using a high-gain electron multiplier, the system delivers exceptional signal-to-noise ratio, low polyatomic interferences, and stable long-term reproducibility. This pre-owned instrument has undergone full functional validation—including sensitivity calibration (e.g., >10⁷ cps/ppq for ²³⁸U), oxide ratio (<2%), and doubly charged ion ratio (<3%)—and meets Agilent’s factory-recommended performance criteria for routine laboratory use. Designed for laboratories requiring regulatory-compliant elemental quantification without capital expenditure on new instrumentation, the Agilent 7800 ICP-MS remains fully compatible with modern sample introduction systems (e.g., autosamplers, laser ablation, hydride generation) and supports isotopic ratio measurements for geochemical or nuclear applications.
Key Features
- Quadrupole mass analyzer with mass range 5–280 u, optimized for rapid scanning and high transmission efficiency
- Collision/reaction cell technology (ORS3™) enabling interference removal via He gas collision mode or H₂/CH₄ reaction mode
- Integrated sample introduction system featuring MicroMist nebulizer, quartz cyclonic spray chamber, and Peltier-cooled interface
- Dual-mode detector (analog + pulse counting) supporting dynamic linear range >10¹²
- Robust RF generator (27 MHz) with automatic impedance matching and plasma stabilization algorithms
- Full compliance with original Agilent hardware architecture—no third-party modifications or non-OEM components
- Factory-reset firmware (v4.4 or later) with all diagnostic logs and calibration history preserved
Sample Compatibility & Compliance
The Agilent 7800 ICP-MS accepts liquid samples across wide matrix ranges (aqueous standards, digested environmental soils, biological fluids, semiconductor-grade acids) and interfaces seamlessly with EPA Method 200.8, ISO 17294-2, and ASTM D5673 protocols. All refurbished units undergo full traceable verification per Agilent’s Performance Verification Procedure (PVP), including daily QC checks (Tune Report, Sensitivity Check, Oxide/Doubly Charged Ratios). The system supports GLP/GMP environments through audit-trail-enabled software logging, user-access controls, and electronic signature compatibility when deployed with compliant LIMS integration. No modifications affect 21 CFR Part 11 readiness—audit trails, data integrity, and operator authentication remain fully functional post-refurbishment.
Software & Data Management
Controlled exclusively via Agilent MassHunter Workstation v4.4 or later (included with valid maintenance license), the platform provides method development, real-time spectral monitoring, isotope dilution quantitation (IDMS), and automated report generation. Raw data (.d files) are stored in vendor-native format ensuring full backward compatibility and long-term archival integrity. MassHunter supports secure network deployment, role-based permissions, and integration with enterprise-level data management systems (e.g., Thermo Fisher SampleManager, LabVantage). All instruments ship with validated backup images of software configuration, instrument method libraries, and calibration databases—enabling immediate operational continuity upon installation.
Applications
- Environmental monitoring: Quantification of As, Cd, Pb, U, and rare earth elements in drinking water (EPA 200.8), wastewater, and sediment extracts
- Pharmaceutical quality control: Residual catalyst metal screening (e.g., Pd, Pt, Rh) in APIs per ICH Q2(R2) and USP /
- Geochemical research: Isotopic fingerprinting of Sr, Nd, Hf, and Pb in rock digests and zircon LA-ICP-MS applications
- Food safety testing: Multi-element analysis of toxic metals (e.g., inorganic As, total Hg) in infant formula, rice, and seafood per EU Commission Regulation (EU) No 2023/915
- Materials science: Impurity profiling in high-purity silicon, lithium battery cathodes, and photovoltaic-grade materials
FAQ
Is this unit eligible for Agilent factory service contracts?
Yes—refurbished Agilent 7800 ICP-MS systems retain full eligibility for Agilent Care extended support plans, provided the serial number is active in Agilent’s global service registry.
What documentation accompanies the instrument?
Each unit ships with a complete refurbishment dossier: PVP test reports, calibration certificates (traceable to NIST SRMs), firmware version log, software license verification, and 12-month warranty terms.
Can it be integrated into an existing MassHunter network?
Yes—the system retains native network stack compatibility and supports domain authentication, centralized license server deployment, and remote diagnostics via Agilent Remote Assist.
Are consumables and spare parts still available?
All OEM consumables (torch assemblies, sampler/skimmer cones, nebulizers, pumps tubing) remain in active production and are available through Agilent’s global distribution channels.
Does the warranty cover detector replacement?
Yes—the 12-month comprehensive warranty includes labor, parts, and detector replacement if performance falls below Agilent’s published specifications during the coverage period.
