The Koehler Halogen Analyzer consists of a manual or automatic sample feed, a two-stage furnace, unit and a microcoulometric titration device. A combination of a quick-heating and programmable IR furnace and a constant-temperature reduction furnace ensure the complete, residue-free combustion of the samples in the oxygen flow. The combustion gases then enter the coulometric detection unit for analysis. Control of the overall system and measurement data evaluation is by means of user-friendly software.
The unique furnace unit of the Koehler Halogen Analyzer consists of a programmable IR furnace with extremely fast heating and cooling rates and coolant-free cooling by means of heat pipes as well as a downstream reduction furnace with a constant temperature.
The sliding cover of the furnace chamber makes this easily observable and accessible: the condition of the combustion tube can be assessed at any time without dismantling.
The heated gas outlet line prevents water condensation. This prevents halogen entrainment and guarantees exact series of measurements. A safety valve protects the furnace against sulphuric acid. Easy dismantling and cleaning.
A closed detection unit offers the discerning user the possibility of tempering and greater safety at work.
Results can be transmitted to LIMS systems.
