 SYSTEM PROGRAM 1 TIC + TOC defines the system
parameters for Oxidation Phase operation in TIC & TOC
analysis mode. In TIC & TOC analysis mode, the TIC and TOC
contents of a sample are measured consecutively by means of a
single sample injection into a single reactor.
 SAMPLE PUMP is a shortcut to Commissioning, Sample Pump
menu. See Section
 CO
15s, 20 l/h
ZERO time (15s by default) with the oxygen flow (20 l/h)
settings.
 A "12_HIGH CO2 IN O2" fault is generated during this phase
and BioTector stops if the CO
CO2 ZERO LINE plus the CO2 ZERO ALARM value (250ppm
by default) for three consecutive reactions. See Section
 TIC ACID specifies the amount of acid reagent (in pulses) to be
20p
injected into the reactor at range 1.
 SAMPLE IN defines the amount of sample (in pulses) to be
7p, P-V
injected into the reactor at operation range 1. P-V stands for
"Pinch Valve", which identifies the type of valve used during
sample injection.
 A single pulse pump operation corresponds to ½ revolution of
the pump roller.
 Note that any change carried out on the factory SAMPLE IN
setting requires recalibration of the system.
 SAMPLE BYPASS PYRGE is the time sample lines are purged
10s, 7l/h
with Oxygen gas flow.
 SAMPLE INJECTION is the time sample is pushed into the
7s, 5l/h
Mixer Reactor using Oxygen gas flow.
 SAMPLE LINE REV FILL is the Sample Pump reverse
15p
operation, to fill the sample lines with oxidized liquid.
 REACTOR VALVE FILL is the Sample Pump reverse operation,
3p
to fill the Reactor Valve with oxidized liquid. This is carried out to
protect the Reactor Valve during oxidation process.
 BioTector sparges and measures the TIC content of the sample
20s, 20 l/h
for the TIC SPARGE TIME (20s by default) with the oxygen flow
(20 l/h) settings.
 If the TIC level does not drop below the TIC CHECK level
(10ppm CO
TIC SPARGE TIME, BioTector automatically extends this time
(extension time) until the TIC level drops below 10ppm level.
 A "50_TIC OVERFLOW" warning is generated and BioTector
keeps running if the TIC level does not drop below 10ppm by 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.
 BASE defines the amount of base (in pulses) to be injected into
230p
the reactor for the reaction at range 1.
 BioTector oxidizes the sample for the BASE OXIDATION time
135s, 10 l/h
(135s by default) with the oxygen flow (10 l/h) settings. If any
CO
the TOC result because the default setting of PEAK
INTEGRATION is TOC+BASE OXID in Result Integration menu.
 TOC ACID states the amount of acid (in pulses) to be injected
210p
into the reactor for the TOC SPARGE phase at range 1.
