TNM-L
Total Nitrogen Unit for TOC-L Series

Perform 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.)

Shimadzu Introduces the TOC-1000e S Online Analyzer for Ultrapure Water Monitoring in Semiconductor Manufacturing
Shimadzu Scientific Instruments introduces the TOC-1000e S Online Total Organic Carbon (TOC) Analyzer, engineered to meet the increasingly stringent ultrapure water quality requirements of advanced semiconductor manufacturing. As semiconductor miniaturization continues to advance, even trace-level organic contamination in ultrapure water can directly impact process stability and yield, making precise, reliable monitoring of TOC essential.
