Elite ICP-OES 1800 Full-Spectrum Direct-Reading Inductively Coupled Plasma Optical Emission Spectrometer

Overview

The Elite ICP-OES 1800 is a high-performance, full-spectrum direct-reading inductively coupled plasma optical emission spectrometer engineered for precise, multi-element quantitative analysis in routine and regulatory laboratory environments. Based on the fundamental principle of inductively coupled plasma atomic emission spectroscopy (ICP-OES), the instrument atomizes and excites liquid samples in a high-temperature argon plasma (~6,000–10,000 K), enabling simultaneous detection of emitted spectral lines across the ultraviolet to near-visible range (165–900 nm). Its solid-state echelle grating spectrometer coupled with a back-thinned, deep-depletion CCD detector ensures high spectral resolution, low stray light, and robust signal-to-noise performance—critical for trace-level elemental quantification in complex matrices. Designed for operational reliability under continuous use, the system integrates a robust RF generator, cooled nebulizer chamber, and integrated peristaltic sample introduction—all optimized to deliver consistent plasma stability and analytical reproducibility.

Key Features

• Full-spectrum acquisition architecture: Captures the entire usable wavelength range (165–900 nm) in a single exposure, eliminating sequential scanning delays and enabling true multi-element analysis without compromise on dwell time or detection limits.
• High-resolution echelle optical system: Delivers resolving power sufficient to separate closely spaced emission lines (e.g., As 193.696 nm and Al 193.696 nm), minimizing spectral interferences in environmental and metallurgical samples.
• Stable plasma operation: Achieves short-term intensity stability <0.01% over 30 minutes—validated using internal standard monitoring (e.g., Y or Sc)—supporting long-duration batch analysis under GLP-compliant workflows.
• Quantitative precision: Demonstrates ≤1.5% relative standard deviation (RSD) for replicate analyses of certified reference materials (CRMs) across concentration ranges from sub-ppb to ppm levels.
• Robust sample introduction: Includes a high-efficiency concentric glass nebulizer, cyclonic spray chamber with Peltier cooling, and peristaltic pump with chemically resistant tubing—optimized for aqueous, acidic, and moderately saline digests.
• Modular hardware design: Supports optional accessories including autosampler integration, UV purge module for sub-200 nm sensitivity enhancement, and optional radial/axial viewing configuration for matrix-specific optimization.

Sample Compatibility & Compliance

The ICP-OES 1800 accommodates a broad range of sample types following standardized digestion protocols—including EPA Method 200.7 (metals in water), ISO 11885 (water and wastewater), ASTM D5191 (petroleum products), and GB/T 5750.6 (drinking water). It is routinely deployed for analysis of acid-digested geological solids (soils, ores), filtered aqueous extracts (groundwater, leachates), digested biological tissues, and purified metal solutions. All hardware and software components are designed to support audit-ready documentation requirements aligned with ISO/IEC 17025:2017, USP <233>, and FDA 21 CFR Part 11 when configured with electronic signature and audit trail modules. System validation packages—including IQ/OQ documentation templates and CRM-based performance verification protocols—are provided to facilitate laboratory accreditation readiness.

Software & Data Management

Controlled via Elite’s SpectraSuite™ v4.x platform, the instrument supports method development, real-time spectral visualization, automated background correction, and multi-point calibration with internal standard normalization. The software enables customizable reporting formats compliant with LIMS interfaces (via ASTM E1384 or HL7 messaging), raw data archiving with SHA-256 checksum integrity verification, and configurable user access levels (administrator, analyst, reviewer). Audit trail functionality logs all critical events—including method edits, calibration updates, result approvals, and data deletions—with immutable timestamps and operator IDs. Data export options include CSV, PDF analytical reports, and XML-formatted results compatible with enterprise-wide QA/QC dashboards.

Applications

• Geology & Mining: Quantitative determination of major (Fe, Al, Ca, Mg), minor (Mn, Ti, Ba), and trace elements (As, Cd, Pb, Hg) in rock, soil, and tailings samples to inform resource estimation, process optimization, and post-mining site remediation planning.
• Precious Metals Refining: Detection of sub-ppb level impurities (e.g., Cu, Ni, Co, Fe) in gold, silver, and platinum group metal (PGM) solutions—essential for purity certification and compliance with LBMA Good Delivery standards.
• Environmental Monitoring: Routine analysis of drinking water, wastewater effluents, and contaminated soils per national regulatory thresholds (e.g., China’s GB 3838-2002, EU WFD 2000/60/EC).
• Petrochemical & Lubricants: Measurement of wear metals (Cr, Fe, Al, Cu) and additive elements (Ca, Zn, P, Mg) in used engine oils and fuels to assess equipment health and formulation integrity.
• Consumer Safety Testing: Screening of regulated heavy metals (Pb, Cd, Cr(VI), Hg, As, Sb, Ba, Se) in children’s toys, plastics, and coatings per EN71-3 and ASTM F963.
• Metallurgy & Alloy Production: Rapid compositional verification of incoming raw materials, molten bath sampling, and final product certification—supporting ISO 9001 and IATF 16949 quality management systems.

FAQ

What sample preparation methods are recommended prior to ICP-OES analysis?
Acid digestion using EPA Method 3050B (for soils/sediments) or 3051A (microwave-assisted) is standard; aqueous samples require filtration (0.45 µm) and acidification to pH <2 with ultrapure HNO₃.
Does the system support both axial and radial plasma viewing configurations?
The ICP-OES 1800 is configured for radial viewing by default; axial mode is available as a factory-installed option requiring optical path recalibration and modified torch positioning.
How is instrument performance verified during routine operation?
Daily performance checks include measurement of sensitivity (Mg II 280.270 nm intensity), background equivalent concentration (BEC), and RSD of a mid-level multi-element standard—recorded in the instrument logbook per ISO/IEC 17025 clause 7.7.
Is the software compliant with 21 CFR Part 11 requirements?
Yes—when deployed with optional electronic signature module, role-based access control, and enabled audit trail, SpectraSuite™ meets predicate rule requirements for electronic records and signatures in regulated pharmaceutical and clinical laboratories.
What maintenance intervals are recommended for optimal long-term stability?
Nebulizer and injector tube cleaning after every 100 samples; torch inspection and alignment every 500 hours; RF matching network calibration quarterly; and full optical alignment annually by certified service engineer.
