Analytik Jena multi N/C 3100 (ChD) Basic Unit TOC/TNb analyzer with multiWin software TNb determination with electrochemical solid state detector Analyzer for fast and precise simultaneous determination of TIC/TOC/TC/NPOC/POC and TNb in aqueous samples in compliance with the following national and international standards like e.g. DIN EN 1484, ISO 8245, EPA 415, ASTM D2579, DIN EN 12260. The PC-system is compliant with FDA CFR 21 Part 11. NDIR detection of the generated carbon dioxide in combination with the VITA method allows extremely precise and reliable TOC analysis even with large sample volumes and at low concentrations. The precise and sensitive TNb determination with a dynamic measuring range can be performed with different detectors chemiluminescence detectors or electrochemical solid state detectors The gas drying system based on physical principles is maintenance-free and does not require the use of chemical drying agents. Sample introduction by flow injection. Sample volumes of up to 1 ml ensure representative sample feed even with inhomogeneous particulate samples. Control of the analyzer is performed by an user-friendly and comfortable high screen performance touch screen in the stand alone version or a control and evaluation unit in the PC version see order no. 450-011.600e. The PC must be ordered separately. A color printer is already included in the scope of delivery of the stand alone units All parameters are displayed and monitored. The graphic display of the measuring process ensures transparent analyses and a reliable assessment of the results. The combination of the multi N/C 3100 with an xyz sampler makes the analyzer an automatically operating analytical system for simultaneous TOC/TNb analysis. With the optional HT 1300 Solids Module, TC/TOC analyses in solid samples is possible, too. A complete set of initial equipment for installation of the multi N/C® 3100 and training of the user, incl. operating manual, consumables and chemicals for up to 1,500 analyses is already included.
