Analytik Jena ICprep Combustion-Based Organic Elemental Analyzer

Overview

The Analytik Jena ICprep is a fully automated combustion-based organic elemental analyzer engineered for precise, high-throughput determination of halogens (fluorine, chlorine, bromine, iodine) and sulfur in organic matrices. It operates on the principle of high-temperature catalytic combustion (up to 1100 °C) followed by selective absorption and quantification—typically via ion chromatography (IC), but also compatible with HR-CS MAS, ISE, or photometric detection. Unlike classical wet-chemical digestion, the ICprep eliminates reagent consumption, minimizes operator intervention, and avoids cross-contamination risks inherent in manual sample preparation. Its design targets laboratories requiring robust, GLP-compliant workflows for AOF (Adsorbable Organic Halides), EOF (Extractable Organic Halides), and TOF (Total Organic Halides) analysis—key parameters in environmental monitoring, pharmaceutical impurity profiling, polymer quality control, and regulatory compliance testing (e.g., EPA Method 1650, ISO 9562, DIN 38409-H17).

Key Features

• Automated high-temperature combustion system with programmable temperature ramping up to 1100 °C, ensuring complete mineralization of recalcitrant organic compounds including polymers, pharmaceuticals, and biomass.
• Integrated sample introduction module enabling seamless switching between liquid (max. 100 µL) and solid (max. 110 mg) samples without hardware modification or recalibration.
• Dual-stage absorption trap configuration optimized for quantitative recovery of HF, HCl, HBr, HI, and SO₂/SO₃ gases into aqueous media, minimizing analyte loss and memory effects.
• Intelligent process optimization algorithms that dynamically adjust oxygen flow, combustion time, and catalyst regeneration cycles based on sample organic load—enhancing safety and reproducibility for heterogeneous matrices.
• Modular architecture supporting direct coupling to external ion chromatographs or other detection systems via standardized PTFE transfer lines and pressure-regulated gas interfaces.
• Robust stainless-steel and quartz construction, CE-marked safety interlocks, and redundant thermal monitoring ensure uninterrupted operation under routine laboratory conditions.

Sample Compatibility & Compliance

The ICprep accommodates diverse sample types: environmental water extracts, polymer leachates, pharmaceutical excipients, food packaging materials, and activated carbon filters. It meets critical regulatory requirements for halogen and sulfur speciation—including EPA 1650/1651, ISO 25101 (AOF), ISO 9562 (total halogens in plastics), and ASTM D7359 (total fluorine in fuels). All method sequences are traceable and audit-ready; instrument logs record combustion parameters, absorption volumes, and run timestamps—supporting FDA 21 CFR Part 11 compliance when paired with validated LIMS or IC software with electronic signature capability. No hazardous acids or oxidants are required, aligning with green chemistry principles (ACS GCI Principles #2, #9).

Software & Data Management

Control and data acquisition are managed via ICprep Control Software—a Windows-based application offering method editor, real-time combustion diagnostics, and integrated calibration curve management. Raw absorption solution data (e.g., IC peak areas) can be imported directly for final concentration calculation. The software supports CSV export, PDF report generation with digital signatures, and configurable pass/fail criteria per USP <643>, EP 2.4.24, or internal SOPs. Audit trails log all user actions, parameter changes, and system events—fully compliant with GLP and GMP documentation standards. Remote monitoring via Ethernet interface enables centralized lab fleet management.

Applications

• Environmental labs quantifying adsorbable/extractable organic halides (AOF/EOF) in wastewater, drinking water, and soil extracts per EPA and ISO protocols.
• Pharmaceutical QA/QC departments verifying halogen content in APIs and intermediates to meet ICH Q3D elemental impurity limits.
• Materials science facilities assessing halogen migration from flame-retardant polymers or sulfur contamination in battery electrode slurries.
• Food safety laboratories screening for residual halogenated pesticides or sulfur-containing preservatives in packaging simulants.
• Research institutions studying organohalogen biodegradation pathways using isotopically labeled substrates—enabled by consistent, low-background combustion performance.

FAQ

What detection techniques are compatible with ICprep output solutions?

Ion chromatography (IC) is the primary detection method, but outputs are also suitable for high-resolution continuum source molecular absorption spectrometry (HR-CS MAS), ion-selective electrodes (ISE), and UV-Vis photometry following appropriate derivatization.

Does ICprep require daily maintenance or catalyst replacement?

The nickel-chromium catalyst bed is designed for >10,000 analyses under standard operating conditions; routine maintenance is limited to weekly quartz tube inspection and monthly absorption vessel cleaning—no consumable catalyst cartridges are required.

Can ICprep analyze fluorine in PTFE or other highly stable fluoropolymers?

Yes—its dual-zone furnace (pre-combustion + main combustion) and optimized oxygen enrichment enable complete defluorination of PTFE at 1100 °C, with quantitative recovery verified against NIST SRM 1643e and CRM 045-050.

Is method validation support available from Analytik Jena?

Yes—application notes, IQ/OQ/PQ protocols, and third-party validation templates aligned with ISO/IEC 17025 are provided with each system installation.
