TRL - online TOC Analyzer

Unique dual temperature zone furnace design assures complete combustion of carbon and nitrogen containing species while preserving catalyst lifetime.

Our distinctive furnace design with two separate temperature zones ensures the thorough burning of carbon and nitrogen compounds, while simultaneously prolonging the lifespan of the catalyst.

The online TOC system by TRL Instruments offers the capability to measure both Total Carbon (TC) and Total Nitrogen (TNb) simultaneously using its optional TN module. The design of the TRL-onlineTOC Analyzer is geared towards simplifying maintenance procedures.
