Analytik Jena multi N/C 2100 Used TOC/TN Analyzer

Overview

The Analytik Jena multi N/C 2100 is a laboratory-grade, dual-parameter elemental combustion analyzer engineered for the simultaneous quantification of total organic carbon (TOC) and total nitrogen (TN) in aqueous, solid, and semi-solid matrices. Its operational principle relies on high-temperature catalytic oxidation—up to 1,000 °C for liquids and 1,500 °C for solids—followed by selective detection: non-dispersive infrared (NDIR) absorption for CO₂ (derived from TOC) and either NDIR, chemiluminescence detection (CLD), or solid-state electrochemical detection (ChD) for nitrogen oxides (NOₓ) generated from TN oxidation. This architecture enables trace-level quantification with sub-part-per-trillion sensitivity and robust performance across heterogeneous sample types—including wastewater, soil extracts, pharmaceutical process streams, and environmental sediments—without requiring method-specific hardware reconfiguration.

Key Features

• Dual-furnace modular design: Independent high-temperature oxidation zones allow concurrent liquid and solid sample analysis; solid module achieves stable operation at 1,300–1,500 °C with optimized catalyst lifetime.
• VITA (Variable Inlet Temperature Adjustment) technology: Dynamically regulates carrier gas flow and thermal equilibration to suppress baseline drift caused by pressure or humidity fluctuations—critical for long-duration batch runs.
• Easy Cal calibration protocol: Single-point standard calibration validated across full dynamic range (0–30,000 ppm TOC); eliminates multi-point curve fitting while maintaining linearity per ISO 8245 and ASTM D7573.
• SCS (Safety Control System): Integrated hardware interlocks monitor furnace temperature, gas pressure, cooling water flow, and catalyst bed integrity; automatically initiates shutdown and purge upon anomaly detection.
• High-salinity & particulate tolerance: Validated for samples containing up to 85 g/L dissolved salts and suspended particles ≤630 µm—enabling direct injection of estuarine water, brine-impacted groundwater, or slurry digests without pre-filtration.

Sample Compatibility & Compliance

The multi N/C 2100 accommodates liquid samples (aqueous solutions, acids, bases, organic solvents), homogenized solids (soils, sediments, plant tissue), and filter-retained particulates mounted on quartz boats. It complies with core regulatory frameworks governing environmental and pharmaceutical testing: EPA Method 415.3 and 9060A, ISO 8245:1999, ASTM D7573-22, USP <643>, and pharmacopeial requirements for TOC system suitability (e.g., oxidizable carbon recovery ≥95%, system precision ≤5% RSD). All firmware and software modules support 21 CFR Part 11-compliant electronic signatures, full audit trails, and user-access controls—fully documented for GLP/GMP audits.

Software & Data Management

Controlled via multiWin v4.x software, the system provides method-driven automation: sequence definition, auto-dilution, spike recovery calculation, and real-time interference diagnostics (e.g., chloride suppression correction, NOₓ cross-sensitivity compensation). Raw chromatograms, calibration reports, and QC summaries are exportable in CSV, PDF, and XML formats compatible with LIMS integration (via ODBC or HL7). Audit trail logs record every parameter change, user login/logout, calibration event, and result modification—including timestamps, operator ID, and reason-for-change fields—meeting ALCOA+ data integrity principles.

Applications

This instrument is routinely deployed in municipal and industrial wastewater treatment plants for compliance monitoring (e.g., discharge permit verification); in pharmaceutical manufacturing for cleaning validation (API residue detection in rinse waters); in academic geochemistry labs for carbon/nitrogen stoichiometry in sediment cores; and in regulatory agencies for certification of drinking water purity per WHO guidelines. Its ability to resolve TC, TOC, NPOC, TIC, POC, and TNb within a single run—without hardware switching—reduces turnaround time and inter-method variability in multi-analyte environmental surveys.

FAQ

Is this unit factory-refurbished or dealer-certified?
This unit has undergone full functional validation by an Analytik Jena–authorized service partner, including furnace temperature mapping, NDIR detector linearity verification, and catalytic converter efficiency testing.
Does it include original documentation and calibration certificates?
Yes—complete set of English-language operating manuals, safety documentation, factory calibration records, and post-refurbishment performance verification report are provided.
Can it be upgraded to support newer software versions or additional detection modules?
multiWin v4.x is the final supported release; no further upgrades are available. However, the hardware platform remains compatible with all legacy accessories (e.g., autosampler AS 3000, solid module SM 2100).
What consumables are required for routine operation?
Primary consumables include quartz combustion tubes, Pt catalyst pellets, CO₂ scrubber cartridges (Ascarite II), NOₓ scrubbers (sodium hydroxide pellets), and certified TOC/TN standards traceable to NIST SRM 1596 and 1597a.
Is remote diagnostic support available post-purchase?
Yes—Analytik Jena’s global service network offers remote connection via secure VPN for troubleshooting, firmware patching, and performance optimization under valid support agreement.
