At this phase, the TOC acid is added to the solution in the reactor and mixed together. The system then
pauses to allow the pH to be tested. The user now has 3 options. Option 4 is used to take the sample as
before, but both options 5 and 6 below will end the test, as the TOC acid check is the last phase in the cycle.
5. Continue To Next Phase. If this is selected, the program continues to the next phase, which is the
reactor purge phase.
6. Stop Test. If this is selected, the program jumps to the reactor purge phase.
As the next phase is the reactor purge phase, the user is prompted to confirm that all tubes have been re-
connected before the BioTector starts this phase.

The pH test is complete. The BioTector will purge the reactor and the CO
