Overview
The Analytik Jena multi EA 5010 N/S is a high-precision, high-throughput elemental analyzer engineered for the simultaneous or independent quantification of nitrogen (N) and sulfur (S) in liquid, gaseous, and liquefied petroleum gas (LPG/LNG) matrices. It employs high-temperature combustion (up to 1150 °C) in an oxygen-rich quartz furnace, followed by selective detection via dual-channel UV-Vis spectrophotometry (for nitrogen oxides) and non-dispersive infrared (NDIR) absorption (for sulfur dioxide). This orthogonal detection architecture ensures high specificity, minimal interferences, and robust performance across complex hydrocarbon streams — critical for petrochemical QA/QC, refinery process control, and regulatory compliance testing. Designed for mission-critical environments, the system operates continuously under unattended 24/7 conditions, delivering reproducible results with trace-level sensitivity and broad dynamic linearity.
Key Features
- HiPerSens dual-detector system: Independent UV-Vis and NDIR channels enable concurrent N and S measurement without cross-talk or reconfiguration delays.
- Ultra-low detection limits: ≤0.5 ppb for nitrogen and ≤0.3 ppb for sulfur, validated per ASTM D7183 and ISO 20846 protocols.
- Short analysis cycle: Full quantification completed in 2–5 minutes, including combustion, gas transfer, detection, and data processing.
- Compact footprint: Instrument dimensions (W × D × H) are 550 × 520 × 480 mm, occupying less than 0.3 m² — optimized for space-constrained labs.
- Intelligent system monitoring: Real-time diagnostics track furnace temperature stability, carrier gas flow, detector baseline drift, and catalyst activity; automatic parameter optimization reduces manual intervention.
- Full remote operability: Secure web-based interface (HTTPS/TLS) enables instrument status monitoring, method execution, and report retrieval from any authorized network endpoint.
Sample Compatibility & Compliance
The multi EA 5010 N/S accepts direct injection of volatile liquids (e.g., gasoline, diesel, jet fuel), pressurized gases (natural gas, refinery off-gas), and cryogenic LNG/LPG samples via integrated pressure-regulated autosamplers. Solid samples require prior dissolution or slurry preparation but are supported via optional high-temperature oxidation modules. All operational workflows comply with internationally recognized standards, including ASTM D5291 (total N in petroleum products), ASTM D7183 (N in middle distillates), ISO 20846 (S in automotive fuels), and EN ISO 14852 (S in aqueous samples). The system supports full audit trails, electronic signatures, and data integrity controls aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements when configured with validated software packages.
Software & Data Management
Control and evaluation are performed using the EA Control Center v3.x software suite — a Windows-based application certified for GLP/GMP environments. It provides method wizards for rapid SOP deployment, customizable calibration curves (single-point, multi-point, bracketing), real-time chromatogram visualization, and automated peak integration using adaptive baseline algorithms. Raw data, metadata, and audit logs are stored in encrypted SQLite databases with configurable retention policies. Export formats include CSV, PDF analytical reports, and XML for LIMS integration. Software validation documentation (IQ/OQ/PQ protocols) and change control records are available upon request for regulated laboratories.
Applications
- Petrochemical QA/QC: Total sulfur and nitrogen screening in gasoline, diesel, kerosene, and biofuels per Euro 5/6 and Tier 3 specifications.
- Refinery process monitoring: Real-time tracking of N/S content in feedstocks, intermediates, and finished products to optimize hydrotreating efficiency.
- Environmental compliance: Measurement of sulfur emissions precursors in natural gas and LNG prior to export or combustion.
- Research & development: Catalyst poisoning studies, fuel formulation optimization, and reaction pathway analysis in heterogeneous catalysis.
- Contract testing laboratories: High-volume, accredited analysis for ISO/IEC 17025-certified service delivery.
FAQ
What sample introduction options are available for gaseous matrices?
The system supports direct gas sampling via a pressure-controlled loop injector with adjustable residence time and helium carrier gas dilution; optional heated transfer lines prevent condensation for LNG/LPG analysis.
Is method validation support provided for regulatory submissions?
Yes — Analytik Jena supplies application notes, system suitability test procedures, and IQ/OQ/PQ documentation templates aligned with USP , EP 2.4.23, and ISO/IEC 17025 requirements.
Can the instrument be integrated into an existing LIMS environment?
Fully supported via ASTM E1384-compliant ASCII/CSV exports and optional OPC UA server module for real-time bidirectional data exchange.
What maintenance intervals are recommended for routine operation?
Furnace quartz tube replacement every 6–12 months (depending on sample load); catalyst regeneration every 3–6 months; daily automated leak and baseline checks reduce unscheduled downtime.
Does the system meet explosion-proof requirements for hazardous area installation?
The base configuration is rated for Zone 2/Class I Div 2; ATEX/IECEx-certified variants (multi EA 5010 Ex) are available for direct installation in classified locations.
