6.2.1 TIC-module
Due to the modular design of the CS-580 (Helios), the analyzer can be upgraded by a module
for Total Inorganic Carbon (TIC) without further modification. For the TIC determination, the
sample is treated with acid in the TIC module.
6.2.2 TIC analysis
The sample is treated with acid in an Erlenmeyer flask inside the TIC-module. The acid
decomposes the carbonates in the sample, creating CO2. The oxygen flow purges the CO2 out
of the flask through the gas flow system to the infrared detector.
