5.5 TIC-determination (optional)
WARNING
W7.0022
Burning of the skin, eyes and respiratory system.
Corrosive substances:
 Corrosive substances can cause burning of the skin, eyes
and respiratory system.
• Refer to the material safety data sheet for the substance
being used.
• Always wear suitable clothing, including protective
gloves and eye protection.
5.5.1 TIC-module
Due to the modular design of the CS-2000, a module for Total Inorganic Carbon (TIC) can be
placed between the resistance furnace and the analyzer. For the TIC determination, the sample
is treated with acid in the TIC module.
TIC and Total Carbon (TC) can be alternatively analyzed without the necessity of modifying the
analyzer.
5.5.2 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.
