3.2 TIC-determination
3.2.1 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.
3.2.2 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.
