SYSTEM PROGRAM 3
SYSTEM PROGRAM 3 TIC + TOC_D
RANGE CHANGE 2-3 150.0 mgC/l
 RANGE CHANGE 2-3 defines the concentration level for the
BioTector to change its range automatically from range 2 to
range 3.
 The RANGE CHANGE 2-3 is typically the top concentration
point of TOC RANGE 2 in System Range Data menu by default.
RANGE CHANGE 3-2 120.0mgC/l
 RANGE CHANGE 3-2 specifies the concentration level for the
BioTector to change its range automatically from range 3 to
range 2.
 The RANGE CHANGE 3-2 is typically 20% less of the top
concentration point of TOC RANGE 2 in System Range Data
menu by default.
RANGE CHANGE 3-1 40.0mgC/l
 RANGE CHANGE 3-1 defines the concentration level for the
BioTector to change its range automatically from range 3 to
range 1.
 The RANGE CHANGE 3-1 is typically 20% less of the top
concentration point of TOC RANGE 1 in System Range Data
menu by default.
SAMPLE IN 0p MF-180
 SAMPLE IN states the amount of sample (in pulses) to be
injected into the reactor at range 3. If the setting is 0p MF-180, it
means that the sample injection at this range will be carried out
by means of the Motorized Fixed 180° rotation of the Sample
(ARS) Valve.
 When SAMPLE IN setting is MF-180, the Sample Pump does
not inject the sample into reactor. Instead acid reagent (or base
reagent depending on the analysis type of the system) and the
carrier gas flow is used to inject the fixed volume of the sample
sitting inside the Sample (ARS) Valve.
BASE INJECTION 2p
 BASE INJECTION defines the amount of base reagent (in
pulses) used to inject the liquid sample into the reactor for the
reaction at range 3.
TIC ACID 3p
 TIC ACID defines the amount of acid reagent (in pulses) to be
injected into the reactor at range 3.
BASE 15p
 BASE specifies the amount of base (in pulses) to be injected into
the reactor for the BASE OXIDATION phase at range 3.
BASE OXIDATION 135s
 BASE OXIDATION defines the oxidation time (150s by default),
which can be programmed independently for range 3.
 If the Base Oxidation time is different than the one programmed
in System Program 1 menu, depending on the difference
between the two settings, the reaction time at range 3 will be
either longer or shorter than the reaction time displayed in
System Program 1 menu.
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 3.
SYSTEM PROGRAM 3 TC_D
SAMPLE IN 1p , M-V
 SAMPLE IN defines the amount of sample (in pulses) to be
injected into the reactor in TC mode at range 3.
ACID IN 2p
 ACID IN identifies the quantity of acid reagent (in pulses) to be
injected into the reactor for the VOC Oxidation phase in TC
mode at range 3.
TC ACID 12p
 TC ACID states the amount of acid (in pulses) to be injected into
the reactor for the TC SPARGE phase in TC mode at range 3.
SYSTEM PROGRAM 3 VOC_D
 All system parameters for SYSTEM PROGRAM 3 VOC_D
analysis mode are covered in System Program 3 TC_D and
System Program 3 TIC + TOC_D above.
