multi N/C 2300 The TOC specialist for direct injection
When every particle counts: Direct injection for particulate samples and small sample volumes
multi N/C 2300 is a high-temperature combustion TOC/TNb analyzer featuring true direct sample injection via a microliter syringe. This unique technology makes it ideal for particulate samples, challenging matrices, and limited sample volumes. Municipal wastewater treatment plants, industrial effluent QC, research laboratories, and pharmaceutical QC laboratories rely on the multi N/C 2300 for its robustness, outstanding particle handling, and highly precise sample dosing even for lowest sample volumes.

For over 15 years, we have been using a direct injection device from Analytik Jena’s multi N/C series for degradability and environmental behavior tests in liquid and solid samples. Our TOC analyzer has consistently proven to be reliable, operating safely even during overnight runs. Its microliter syringe and septum-free oven head ensure precise dosing of smallest volumes. We value its robustness, easy maintenance and the fast, reliable support from our partner Analytik Jena.
Dr. Dietmar Kuhn, Managing Director, Laus GmbH (works with multi N/C 2300)
True direct injection without compromise
Multi N/C 2300 works entirely without valves or hoses. A microliter syringe injects the sample top down and directly from the vial into the combustion tube. This eliminates clogging, carryover, and ensures that the entire TOC/TNb load of the sample is introduced into the analyzer for accurate and reproducible results.
