LIQUID PHASE PROGRAM
 LIQUID PHASE PROGRAM defines the system parameters for
Liquid Phase operation in TN analysis mode.
WAIT FOR SMPL 5s
 WAIT FOR SAMPLE is a delay time applied when the reactor
purge of the oxidized sample is completed.
SAMPLE RETURN 28p , 13s
 SAMPLE RETURN specifies the Nitrogen Pump (N Pump)
reverse operation time (programmed by the number of pulses) to
return the oxidized sample back into the oxidized sample catch-
pot/cleaning vessel after the TN measurement.
TN SMPL FETCH 21p , 10s
 TN SAMPLE FETCH defines the Nitrogen Pump forward
operation time to fill the TN measuring cell for TN measurement.
TN SMPL MEASURE 3
 TN SAMPLE MEASURE is the number of TN measurements
taken on sample.
TN SMPL CELL SHIFT 2p , 1s
 TN SAMPLE CELL SHIFT specifies the Nitrogen Pump forward
operation time to shift the sample content of the TN measuring
cell before each measuring cycle. This is carried out to remove
any bubbles, which may be trapped inside the cell.
N CELL PURGE 35p , 16s
 NITROGEN CELL PURGE is the Nitrogen Pump reverse
operation time to purge and empty the contents of the TN
measuring cell.
OSCP PURGE 50p , 24s
 OXIDIZED SAMPLE CATCH POT (OSCP) PURGE is the
Nitrogen Pump forward operation time to empty the oxidized
sample catch-pot/cleaning vessel.
OSCP LINE PURGE 2s
 OXIDIZED SAMPLE CATCH POT LINE PURGE is the BioTector
Sample Pump reverse operation time to remove the remaining
sample from the oxidized sample catch-pot/cleaning vessel.
CLEAN-N CELL FILL 21p , 10s
 CLEANING NITROGEN CELL FILL is the Nitrogen Pump
forward operation time to clean the TN measuring cell.
CL.-SMPL LINE FILL 8p , 3s
 CLEANING SAMPLE LINE FILL is the Nitrogen Pump reverse
operation time to place the TN cleaning solution inside the TN
measuring cell into the oxidized sample catch-pot/cleaning
vessel.
CL.-SMPL LINE PURGE 10p , 4s
 CLEANING SAMPLE LINE PURGE is the Nitrogen Pump
forward operation time to take the TN cleaning solution from the
oxidized sample catch-pot and to place it back into the TN
measuring cell.
WASH CYCLES 2
 WASHING CYCLES is the number of DI Water washing cycle,
which takes place after the TN cleaning cycle.
WASH-N CELL FILL 23p , 11s
 WASHING NITROGEN CELL FILL is the Nitrogen Pump forward
operation time to wash the TN measuring cell with DI water.
W.-SMPL LINE FILL 12p , 5s
 WASHING SAMPLE LINE FILL is the Nitrogen Pump reverse
operation time to place the DI water inside the TN measuring cell
into the oxidized sample catch-pot/cleaning vessel.
W.-SMPL LINE PURGE 16p , 7s
 WASHING SAMPLE LINE PURGE is the Nitrogen Pump forward
operation time to take the DI water from the oxidized sample
catch-pot and to place it back into the TN measuring cell.
DIW-N CELL FILL 21p , 10s
 DI WATER NITROGEN CELL FILL is the Nitrogen Pump
forward operation time to fill the TN measuring cell with DI water.
DIW MEASURE 3
 DI WATER MEASURE is the number of DI water reference
measurements taken on the DI water in TN measuring cell at the
corresponding wavelengths.
DIW CELL SHIFT 1p , 0.5s
 DI WATER CELL SHIFT specifies the Nitrogen Pump forward
operation time to shift the DI water content of the measuring cell
before each DI water reference measuring cycle. This is carried
out to remove any bubbles, which may be trapped inside the
cell.
