Analytik Jena multi X 2500 Total Organic Halogen (AOX) and Total Halogen (TX) Analyzer

Overview

The Analytik Jena multi X 2500 is a fully automated, combustion-based total organic halogen (AOX) and total halogen (TX) analyzer engineered for high-precision determination of adsorbable organic halogens (AOX), total organic halogens (TOX), extractable organic halogens (EOX), persistent organic halogens (POX), and total halogens (TX) in diverse environmental and industrial matrices. It operates on the principle of high-temperature catalytic combustion (950 °C) followed by microcoulometric detection of halide ions—enabling quantification at sub-µg/L levels in aqueous samples and sub-µg/g levels in solids. The system complies with internationally recognized standard methods including ASTM D5907 (for AOX in water), ISO 9562 (AOX in water and wastewater), DIN 38409-H16 (German standard for AOX), and EN 1485 (determination of AOX in water). Its robust architecture supports routine compliance monitoring in accredited environmental laboratories, wastewater treatment facilities, and industrial QA/QC departments operating under GLP or ISO/IEC 17025 frameworks.

Key Features

• Integrated sample preparation module enabling automated adsorption, filtration, acidification, and extraction for AOX/TOX analysis—reducing manual handling and contamination risk.
• High-efficiency quartz combustion tube with platinum catalyst for complete oxidation of organic halogen compounds across complex matrices (e.g., sludge, sediments, fuel oils, PMMA waste).
• Microcoulometric titration cell with real-time charge integration for selective, interference-resistant halide quantification—no chromatographic separation required.
• Modular automation options: auto-sampler (up to 48 positions), robotic liquid handler, and optional solid-sample introduction unit for direct analysis of powders, chips, or filter residues.
• Self-diagnostic system with continuous monitoring of gas flow, combustion temperature, electrolyte level, and electrode response—ensuring analytical continuity and traceable instrument performance.
• Pre-installed method packages aligned with ASTM, ISO, and DIN protocols—allowing rapid deployment for drinking water, groundwater, industrial effluents, and hazardous waste characterization.

Sample Compatibility & Compliance

The multi X 2500 accommodates a broad spectrum of sample types without modification to core hardware: liquid samples (drinking water, surface water, leachates, process streams), suspended solids (slurries, activated sludge), dried solids (sediments, soils, wood preservatives), and challenging organics (used lubricants, polymer residues, halogenated solvents). All analyses adhere to regulatory data integrity requirements: audit trails, electronic signatures, and user-access control are embedded within the software to support FDA 21 CFR Part 11 compliance where applicable. Method validation reports—including LOD/LOQ, recovery (85–115% per ISO 9562), precision (RSD < 5% for n ≥ 6), and matrix spike fidelity—are generated automatically and exportable in PDF or CSV formats.

Software & Data Management

The instrument is controlled via the JOA (Jena Online Analysis) software platform—a Windows-based application designed for regulated laboratory environments. JOA provides full lifecycle data management: method setup with parameter locking, sequence scheduling, real-time chromatogram-like signal visualization (coulometric current vs. time), automatic peak integration, calibration curve generation (linear or quadratic), and uncertainty propagation per GUM guidelines. All raw data, metadata, and processing steps are stored in a secure, timestamped database with immutable audit logs. Export formats include XML (for LIMS integration), PDF analytical reports, and Excel-compatible result tables. Software updates follow a documented change control process compliant with ISO/IEC 17025 Clause 7.6.

Applications

• Environmental monitoring: Routine AOX screening of municipal wastewater discharges and receiving waters per EU Water Framework Directive reporting requirements.
• Industrial compliance: TOX verification in chemical manufacturing effluents, chlorinated solvent recycling streams, and pulp & paper mill bleach plant discharges.
• Hazardous waste assessment: Quantification of residual halogen content in incineration ash, contaminated soils, and end-of-life plastics prior to landfill disposal (EN 12457 series).
• Petroleum sector: TX analysis in crude oil fractions, refinery sludges, and drilling muds to assess halogen-induced corrosion potential.
• Research & development: Reaction pathway tracking in halogenation/dehalogenation studies, catalyst efficiency evaluation, and fate-and-transport modeling of persistent halogenated pollutants.

FAQ

What regulatory standards does the multi X 2500 directly support?
ASTM D5907, ISO 9562, DIN 38409-H16, EN 1485, and EPA Method 1650 (adapted via combustion optimization).
Can the system analyze solid samples without prior digestion?
Yes—solid samples (e.g., sediments, filters, polymers) are introduced directly into the combustion boat; no acid digestion or solvent extraction is required for TX determination.
Is method validation documentation provided with the instrument?
Yes—factory-verified IQ/OQ documentation, blank/standard/recovery test data, and a comprehensive validation template aligned with ISO/IEC 17025 are included.
How is carryover minimized during high-concentration sample analysis?
The system employs dual-stage quartz trap regeneration, post-combustion gas purging, and automated cell electrolyte refresh—validated to maintain carryover below 0.5% (per ISO 9562 Annex C).
Does the software support remote monitoring and troubleshooting?
JOA includes secure remote desktop capability (with user permission logging) and diagnostic telemetry export for proactive technical support—compatible with corporate IT security policies.
