BASE OXIDATION 300s 10l/h
 BioTector oxidizes the sample for the BASE OXIDATION time
(300s by default) with the oxygen flow (10 l/h) settings. If any
CO
2
is released during this phase, it is measured and added to
the TOC result because the default setting of RESULT
INTEGRATION is TOC+BASE OXID in Result Integration menu.
TOTAL BASE IN 15p
 TOTAL BASE IN defines the amount of base (in pulses) to be
injected into the reactor for the reaction at range 1. Note that the
total pulses of base reagent injected in the BASE OXIDATION
phase is TOTAL BASE IN minus the BASE PURGE.
TOC SPARGE TIME 150s 40l/h
 BioTector sparges and measures the TOC content of the sample
for the TOC SPARGE TIME (150s by default) with the oxygen
flow (40 l/h) settings.
 If the TOC level does not drop below the TOC CHECK level
(350ppm CO2 by default in Reaction Check menu) at the end of
TOC OXIDATION TIME, BioTector automatically extends this
time (extension time) until the TOC level drops below 350ppm
level.
 A “51_TOC OVERFLOW” warning is generated if the TOC level
does not drop below 350ppm at the end of the maximum
extension time, which is 300 seconds. The maximum extension
time is not a programmable function. It is a fixed figure within the
system software.
TOC ACID 12p
 TOC ACID states the amount of acid (in pulses) to be injected
into the reactor for the TOC SPARGE phase at range 1.
TOC OXIDATION 75s
 TOC OXIDATION determines the time (75s by default), the
ozone generator will be running at the start of the TOC Sparge
phase. Note that TOC OXIDATION time is part of the TOC
Sparge phase and does not increase the TOC SPARGE TIME.
REACTOR PURGE 30s 80l/h
 BioTector purges the reactor for the REACTOR PURGE time
(30s by default) with the oxygen flow (80 l/h) settings.
COOLER PURGE 1s
 BioTector purges the cooler of a build up of liquid for the
COOLER PURGE time (1s by default) setting.
PRESSURE CHECK 25s
 PRESSURE CHECK displays the overall duration (25s by
default) of the pressure check test, if activated (by 6.0 l/h default
setting) in Sequence Program, Pressure/Flow Test Program
menu. During the pressure check, system performs an automatic
test at the end of each reaction by pressurizing the relevant
system components with oxygen gas and detecting any gas leak
using the mass flow controller. The pressure check cycle is a
safety measure, which ensures that there is no gas leak in the
system and it is safe to start the next analysis reaction.
 If system detects any leak during the pressure check for the
number of consecutive reactions (3 by default, programmed by
PRESSURE CHECK COUNT in Sequence Program,
Pressure/Flow Test Program menu), the pressure check fails
and BioTector generates a “06_PRESSURE CHCK FAIL” fault
and stops. This fault is logged in the fault archive.
ANALYZER PURGE 15s 40l/h
 BioTector purges the CO
2
analyzer for the ANALYZER PURGE
time (15s by default) with the oxygen flow (40 l/h) settings.
REACTION TIME 6m45s
 REACTION TIME displays the total reaction time (in minutes and
seconds) for range 1, based on all programmed settings above.
