TOC combustion tube
The TOC combustion tube (reactor) is used to determine the TC, TOC and NPOC param-
eters in water samples. The combustion tube is made of quartz glass and is filled with a
catalyst and additives. If the effectiveness of the catalyst decreases, the combustion tube
has to be filled again.
