Analytik Jena multi EA H 5000 Sulfur and Nitrogen Analyzer

Overview

The Analytik Jena multi EA H 5000 Sulfur and Nitrogen Analyzer is a high-precision, multi-element combustion-based elemental analyzer engineered for the quantitative determination of total sulfur (S), total nitrogen (N), total carbon (C), and total chlorine (Cl) in diverse sample matrices—including liquids, gases, liquefied petroleum gas (LPG), and solid materials. Built upon a robust dual-furnace architecture, the system integrates both vertical and horizontal combustion configurations within a single platform, enabling method-optimized thermal decomposition without hardware reconfiguration. Combustion occurs at up to 1100 °C in an oxygen-rich environment, ensuring complete oxidation of heteroatoms into measurable gaseous species (e.g., NO_x, SO₂, CO₂, HCl). Detection relies on orthogonal, element-specific methodologies: chemiluminescence detection (CLD) for nitrogen; ultraviolet fluorescence (UVF) or microcoulometric titration for sulfur; microcoulometry for chlorine; and non-dispersive infrared (NDIR) spectroscopy for carbon. This modular detection strategy supports simultaneous or sequential analysis with trace-level sensitivity and broad dynamic range—spanning from sub-ppm concentrations to percent-level content.

Key Features

• Dual-furnace design: Switch between vertical and horizontal combustion modes via software command—no manual furnace or combustion tube replacement required.
• Patented flame sensor technology: Real-time monitoring of combustion stability enables adaptive control of sample introduction rate, mitigating risks of flash ignition, carbon deposition, and incomplete oxidation.
• Integrated, heated filtration system: Prevents condensate formation and protects downstream membrane dryers and detectors from moisture and particulate contamination—minimizing maintenance intervals.
• Stabilized gas supply architecture: Integrated pressure regulation and continuous monitoring ensure measurement integrity across inlet oxygen pressures from 0.2–0.6 MPa; automatic alarm triggers for under/over-pressure conditions.
• Intelligent auto-calibration: Single calibration curve accommodates full concentration range (0.0x ppm to % w/w); auto-range switching eliminates manual dilution or method revalidation.
• Fully automated sample handling: Compatible with interchangeable autosamplers for liquids (1–100 µL), solids (up to 100 mg), gases (up to 100 mL), and LPG (1–50 µL), all featuring temperature-invariant gas-phase injection and programmable parameter storage.

Sample Compatibility & Compliance

The multi EA H 5000 accommodates heterogeneous sample types per ASTM D5291, D7183, D7042, ISO 14596, ISO 20846, and IP 541 standards. Liquid samples include fuels, lubricants, solvents, and petrochemical intermediates; gaseous inputs cover natural gas, refinery off-gas, and syngas; solid matrices span catalysts, polymers, coal, and environmental solids. LPG analysis complies with EN 15470 and ASTM D7622 requirements. The system’s hardware and firmware support GLP/GMP-compliant operation, including audit-trail-enabled software (per FDA 21 CFR Part 11), electronic signature capability, and secure user access levels. All combustion and detection modules are CE-marked and conform to IEC 61010-1 safety standards.

Software & Data Management

Control and data acquisition are managed through the proprietary multiWin software suite, a Windows-based platform supporting method development, instrument diagnostics, real-time process visualization, and automated report generation. Software modules enforce data integrity through time-stamped raw signal logging, metadata embedding (operator ID, sample ID, calibration status), and encrypted database storage. Calibration curves, QC checks, and system suitability tests are fully configurable and exportable in CSV, PDF, or XML formats. Remote monitoring and troubleshooting are enabled via secure TCP/IP interface, compatible with enterprise LIMS integration using ASTM E1384 or HL7 messaging protocols.

Applications

The multi EA H 5000 serves critical quality control and R&D functions across petroleum refining, chemical manufacturing, environmental testing laboratories, and pharmaceutical excipient characterization. Typical use cases include sulfur speciation in ultra-low-sulfur diesel (ULSD) per ASTM D7042; nitrogen quantification in jet fuel per ASTM D7183; chlorine screening in PVC stabilizers; total carbon assessment in activated carbon or catalyst supports; and regulatory compliance testing for EPA Method 1664, ISO 8217, and EN 590. Its dual-furnace flexibility ensures optimal recovery for thermally labile compounds (e.g., nitroaromatics) and refractory matrices (e.g., coke, graphite) alike.

FAQ

Can the same autosampler handle both liquid and solid samples?
Yes—the integrated solid/liquid autosampler uses a universal sample carrier tray and programmable needle positioning, eliminating mechanical conversion steps.
Does the system require daily recalibration?
No—calibration stability is maintained over extended runs; routine verification with certified reference materials (CRMs) is recommended per ISO/IEC 17025 guidelines.
How does the flame sensor improve measurement reproducibility?
By dynamically adjusting injection speed based on real-time flame luminosity and stability, it prevents transient combustion anomalies that cause signal drift or peak distortion.
Is compliance with 21 CFR Part 11 supported out-of-the-box?
Yes—multiWin includes role-based authentication, electronic signatures, and immutable audit trails configured to meet FDA requirements.
What maintenance is required for the NDIR detector?
The NDIR module features sealed optical cells and self-diagnostic routines; no consumables or periodic alignment is needed under normal operating conditions.
