TNM-L | Total Nitrogen Unit for TOC-L Series
The Shimadzu TNM-L, Total Nitrogen Unit, performs simultaneous TOC and TN Measurements.
- 720 °C catalytic thermal decomposition/chemiluminescence methods are adopted for TN measurement. There is no interference from metallic ions or bromine in sea water.
- Measurements over a wide range with a detection limit of 5 μg/L for TOC-LCH to an upper limit of 10,000 mg/L.
(In the case of simultaneous TOC/TN measurement, TOC analysis using high-sensitivity catalysts is impossible.)
