 LIQUID PHASE PROGRAM defines the system parameters for
Liquid Phase operation in TN analysis mode.
5s  WAIT FOR SAMPLE is a delay time applied when the reactor
purge of the oxidized sample is completed.
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 SAMPLE FETCH defines the Nitrogen Pump forward
21p , 10s
operation time to fill the TN measuring cell for TN measurement.
3  TN SAMPLE MEASURE is the number of TN measurements
taken on sample.
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.
35p , 16s  NITROGEN CELL PURGE is the Nitrogen Pump reverse
operation time to purge and empty the contents of the TN
measuring cell.
50p , 24s  OXIDIZED SAMPLE CATCH POT (OSCP) PURGE is the
Nitrogen Pump forward operation time to empty the oxidized
sample catch-pot/cleaning vessel.
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.
21p , 10s  CLEANING NITROGEN CELL FILL is the Nitrogen Pump
forward operation time to clean the TN measuring cell.
 CLEANING SAMPLE LINE FILL is the Nitrogen Pump reverse
8p , 3s
operation time to place the TN cleaning solution inside the TN
measuring cell into the oxidized sample catch-pot/cleaning
vessel.
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.
2  WASHING CYCLES is the number of DI Water washing cycle,
which takes place after the TN cleaning cycle.
 WASHING NITROGEN CELL FILL is the Nitrogen Pump forward
23p , 11s
operation time to wash the TN measuring cell with DI water.
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.
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.
21p , 10s  DI WATER NITROGEN CELL FILL is the Nitrogen Pump
forward operation time to fill the TN measuring cell with DI water.
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.
 DI WATER CELL SHIFT specifies the Nitrogen Pump forward
1p , 0.5s
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.
