multi N/C 2300 Series

Analytik Jena – multi N/C 2300 Series

The Specialist – A combustion analyzer specifically designed for handling particle-rich samples and those available in very small volumes, ensuring accurate and reliable results even under challenging conditions.

Sophisticated Technologies for Particle-Rich Samples and Small Volumes – multi N/C 2300 Series

Challenging sample matrices and demanding applications require a robust and intelligent analytical system. The multi N/C 2300 series meets these demands with innovative design and advanced technology. Its septum-free direct injection system, using microliter syringes, is equipped with an efficient rinsing mechanism that effectively prevents blockages and sample carryover—even when handling particle-rich or emulsion-like samples.

At the heart of the system lies the wide-range focus radiation NDIR detector, which allows for an extensive measurement range from 0 to 30,000 mg/L TOC. This enables direct analysis without the need for sample dilution. The Easy Cal function ensures long-term calibration stability and precise standard recovery. Additionally, the VITA flow management system guarantees reliable performance by automatically compensating for gas flow fluctuations.

For automatic sample handling, the AS 60 autosampler streamlines the workflow with integrated acidification, purging, and magnetic stirring for effective homogenization of liquid samples. An optional 112-position rack for 2 mL HPLC vials further enhances sample capacity and throughput.

The system also supports TC and TOC analysis in solid samples. The dual furnace module provides catalytic combustion at up to 950 °C within the instrument, while the HT 1300 solids module offers catalyst-free combustion up to 1800 °C (with additives) in a ceramic combustion tube. Solid samples of up to 3 grams can be introduced horizontally in ceramic boats—no foil wrapping required. The solids module is available as part of the fully automated multi N/C 2300 duo or can be retrofitted with manual or automated sample introduction as needed.

For nitrogen analysis, the instrument can be optionally equipped with a ChD (electrochemical detector) or an advanced CLD (chemiluminescence detector), either integrated during initial configuration or added later as an upgrade.

With its flexibility, durability, and high-performance design, the multi N/C 2300 series is the ideal choice for laboratories working with complex sample matrices, low volumes, and strict analytical requirements.

TOC/TNb Analysis for Particle-Rich Samples and Specialized Applications

The multi N/C 2300 series is specifically designed for demanding applications involving particle-rich samples. Utilizing direct injection technology, these compact and robust analyzers eliminate sample carryover and prevent blockages—even when handling complex liquid matrices. Their modular design allows easy customization for solid sample analysis and the simultaneous measurement of total nitrogen (TNb), offering exceptional versatility.

With septum-free injection via microliter syringes, even the smallest sample volumes can be analyzed precisely—ideal for scientific and pharmaceutical research. For example, in the total nitrogen-based determination of protein content in vaccines, the system enables fast, accurate measurements without cross-contamination and within a broad concentration range.

• Outstanding particle handling with no carryover or blockages in the dosing path

• Direct analysis of undiluted samples, eliminating the need for time-consuming pre-dilution

• New intuitive software with live results display and an optional 21 CFR Part 11-compliant pharma module

• Reduced operator workload thanks to the VITA flow management system, ensuring long-term calibration stability

• Automated workflows including acidification, purging, and sample homogenization

• Five-year warranty on both the wide-range focus radiation NDIR detector and furnace components

With its reliable performance and flexible configuration, the multi N/C 2300 is the perfect solution for laboratories working with challenging samples and strict quality standards.
