Confirm the HCl Water Pump (if fitted for FMI Circulation Pump) is pumping correctly. The
pump rate should be between 8.5ml and 11.5ml in ~18 seconds.
Confirm the WMM60 Sample Pump is pumping correctly. The pump rate at 16 pulses should
be between 5.5ml and 7.5ml in ~8 seconds.
Confirm that the Exhaust, Sample Out, TOC Acid and Base Valves are working. Note that the
Base Valve is optional.
Confirm that the Sample (ARS) Valve is working.
Confirm the MFC is working and pressure on the BioTector oxygen regulator is 350 mbar at
20 l/hr.
Additional requirements for the TN system (next 2 items):
Using the Simulate, Liquid Phase Simulate menu, check the following:
Confirm the WMM60 Nitrogen Pump (N Pump) is pumping correctly. The pump rate at 16
pulses should be between 6.5ml and 7.5ml in ~8 seconds. The pump rate can be measured
by supplying DI Water or tap water to the pump at the inlet port using a small container.
Confirm that all installed valves in the TN system are operating correctly, using the Liquid
Phase Simulate menu.
Go to Operation, Reagents Setup, Install New Reagents menu, confirm the menu items and
select the “START NEW REAGENT CYCLE” function for the system to prime the reagents
and set the Zero Adjust (zero offset) values automatically.
Confirm that the automatic pressure/flow test is passed when analyzer is started up.
When the Zero Calibration cycle is completed, go to Operation, Start Stop menu and stop the
analyzer. Run 5 reactions on DI Water using the manual sample port. If manual port is not
available, use the input point for stream 1, but first set the Sample Pump REVERSE time to 0
seconds in Sample Pump menu. Confirm that the zero response is correct. If the BioTector
has been in storage for a long period, a second “Install New Reagents” cycle may be
required.
If the zero readings and CO
2
peaks are correct, items from 1 to 6 below can be skipped.
Confirm that the pH in the reactor is correct, using the test sequence in the pH Test
menu. See pH Test section in BioTector user manual for details.
Check for a pH of 0 during the TIC phase.
Check for a pH of 14 during the Base Oxidation phase.
Check for a pH of 0 during the TOC phase.
Run a further 2 reactions on DI Water.
Run an “Install New Reagents” cycle on the system to adjust the zero offset.
