High-temperature catalytic combustion analyser for simultaneous TOC and total nitrogen in demanding samples.
The QP1680 uses a high-temperature catalytic furnace instead of liquid reagents, so it handles particle-heavy municipal, mining and industrial samples that clog standard analysers. CO₂ is measured by NDIR and NO by chemiluminescence, giving TOC and TN from one 3–4 minute run.
