QP1680 TOC/TN Combustion Analyser
High-temperature catalytic combustion analyser for simultaneous TOC and total nitrogen in demanding samples.
- TOC
- + TN together
- 800 µm
- particles
- 3–4
- min per run

Laboratory TOC analyser that combines acid, oxidiser and dilution water into a single reagent.
Measures
The QbD1200 removes TIC, converts organic carbon to CO₂ and measures it on the detector. Its single combined reagent reduces reagent cost and carryover, and it needs annual rather than monthly service.
