multi N/C 2300 Series The Specialist
- Compact and robust
- Optimal particle handling without sample carryover
- Suitable for the smallest sample volumes (injection volumes: 10 - 500 µl)
- Easy handling and optimized processes
- New intuitive software with live results display
The specialist: A combustion device specializing in the analysis of particle-rich samples and samples that are only present in small volumes.
TOC/TNb analysis for particle-rich samples and special applications
Thanks to the use of direct injection technology, the compact and robust devices of the multi N/C 2300 series are ideal for particle-rich samples. Their modular design makes them customizable for solids as well as for the simultaneous measurement of nitrogen. The septum-free direct injection prevents sample carryover when handling particle-rich liquid samples. Injections from the microliter syringe make it possible to dose extremely small sample volumes, for example for scientific applications. When determining total protein content via total nitrogen analysis in vaccines, these devices offer impressively short measurement times, no carryover and a broad working range.
- Exceptional particle handling without any blockage or carryover along the sample path
- Analysis of undiluted samples makes laborious pre-dilution steps redundant
- New intuitive software with live result display and 21 CFR Part 11 compliant pharma module
- Reduced workload for staff thanks to the unique VITA flow management system that
- Ensures long-term stable calibrations
- Automatic acidification, purging and sample homogenization
- Five-year warranty on the wide-range focus radiation NDIR detector and the furnace technology

Sophisticated technologies for particle-rich samples and small sample quantities
Difficult matrices and demanding applications need a robust device. The septum-free direct injection from the microliter syringe of the multi N/C 2300 series uses efficient rinsing technology to effectively prevent blockages of the dosing path and any sample carryover even for particle-rich or emulsion-like samples.
The wide-range focus radiation NDIR detector forms the basis of this measuring technology. A broad measurement range of 0 to 30,000 mg/L TOC means that samples can be measured directly without any need for sample dilution. The Easy Cal function enables automatic calibration with long-term stability and reliable standard recovery. The VITA flow management system delivers these benefits by effectively compensating for gas flow fluctuations.
For automatic sample introduction, the autosampler AS 60 offers automatic acidification and purging, as well as magnetic stirring to homogenize liquid samples. A 112 position sample rack for 2 ml HPLC vials is optionally available.
TC and TOC in homogeneous solid samples can be measured with the double furnace module by means of catalytic oxidation at temperatures up to 950 °C in the internal furnace of the multi N/C 2300. In addition, the HT 1300 presents a solids module for catalyst-free combustion of solid samples at up to 1800 °C (with additives) in a ceramic combustion tube. Horizontal sample introduction via ceramic boats enables the direct analysis of solid samples weighing up to 3 g without needing to wrap them into foil. This solids module is part of the multi N/C 2300 duo system including automation, or can be retrofitted with manual or automatic sample introduction at any time.
To measure nitrogen, a reliable electrochemical detector (ChD) can optionally be integrated in the device. Alternatively, a chemiluminescence detector (CLD) can be added as a separate detector module - either during initial analyzer configuration or later.
