CHNS / O analysers - Precise determination for your laboratory
With durable technology, simple maintenance and comprehensive service, we support you throughout the entire life cycle of your analysis system.
Our CHNS / O analysers at a glance
We offer two systems for the precise measurement of CHNS / O that can be flexibly adapted to your requirements:
The CN 802 is a combustion analyser for the determination of carbon (e.g. total carbon – TC, total organic and inorganic carbon after acidification – TOC, TIC), nitrogen (total nitrogen – TN) and C/N ratio in organic matrices. The system enables fast, simultaneous analysis in just 5 minutes and is designed for 24/7 continuous operation. Up to 117 samples can be processed efficiently with the electronic autosampler.
The EMA 502 is a versatile micro elemental analyser for the determination of hydrogen, nitrogen, oxygen, carbon and sulphur. It enables the analysis of solid, semi-solid and liquid samples with a carbon content of up to 20 mg. The system is designed for 24/7 continuous operation throughout the year.
