SYSTEM PROGRAM 2 TC
SAMPLE IN 5p , P-V
▪
SAMPLE IN defines the amount of sample (in pulses) to be
injected into the reactor in TC mode at range 2.
SYSTEM PROGRAM 2 VOC ▪ All system parameters for SYSTEM PROGRAM 2 VOC analysis
mode are covered in System Program 2 TC and System
Program 2 TIC + TOC above.
SYSTEM PROGRAM 3
SYSTEM PROGRAM 3 TIC + TOC
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 3p P-V ▪ SAMPLE IN states the amount of sample (in pulses) to be
injected into the reactor at range 3.
TIC ACID 12p ▪ TIC ACID defines the amount of acid reagent (in pulses) to be
injected into the reactor at range 3.
BASE 70p
▪
BASE specifies the amount of base (in pulses) to be injected into
the reactor for the BASE OXIDATION phase at range 3.
BASE OXIDATION 130s
▪
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 58p ▪
TOC ACID states the amount of acid (in pulses) to be injected
into the reactor for the TOC SPARGE phase at range 3.
