Please note! Display isn’t functioning! So testing isn’t possible.

TOC stands for Total Organic Carbon.
Non-purgable organic carbon is measured by acidifying samples to a pH less than 2.0 and sparging with CO2 free air.
A combustion/non-dispersive infrared gas analysis method is employed.  High purity carrier gas, moistened by a humidifier, flows at a rate of 150 mL/min.
The sample is injected into a TC (Total Carbon) combustion tube, which has been filled with oxidation catalyst and heated to 680°C.  
The sample is combusted or decomposed to CO2.  
The combustion product is sent through an IC reaction vessel, cooled, dried by a dehumidifier and then sent through a halogen scrubber.  
The NPOC component is detected for CO2 in a non-dispersive infrared gas analyzer (NDIR).  
The peak area count is proportional to the NPOC concentration of the sample.
