14.14.3 Regenerating the TIC reactor
WARNING
Risk of chemical burns
The TIC reactor is regenerated and cleaned with 40 % phosphoric acid. Phosphoric acid
can irritate eyes, skin and mucous membranes.
¡
Wear protective clothing when handling the concentrated acid.
¡
Observe all notes and specifications in the safety data sheet.
NOTICE
Risk of leaks
A cannula that is too large will damage the septum on the septum port.
¡
Only use cannula with an outer diameter of 0.63 mm for the septum port.
ð
For TIC determination or TIC determination in differential mode: The TIC reactor
must be regenerated daily. How often this must be done is dependent on the TIC
content of the samples. For high TIC content, regenerate the TIC reactor more than
once daily.
ð
Regeneration of the TIC reactor is also required after longer times of inactivity.
ð
If only the TC or NPOC mode is used, regeneration of the TIC reactor is not required.
