4. Why B3500ul model was developed?
The “ul” version of BioTector enables detection of ppb level TOC changes
ppb TOC level changes are an early indication of corrosion or inefficient operation in critical equipment such as turbines and (ultra) pure water RO systems
Key markets include: (Petro)Chemical, Power, SemiCon. and other markets where TOC is measured
The “ul” product enhances the portfolio of BioTector products by delivering resolution of ±2% or 10ppb detection capabilities

5. B3500ul Analyser performance – accuracy and linearity
BioTector’s Product Leadership in the on-line analyser market is characterized by reliable and trusted TOC analysis
+2%
-2%
B3500ul achieves excellent stability which can be demonstrated during long term tests where specified ±2% accuracy is maintained .
BioTector B3500ul has an excellent linear response across the entire ppb range.

6. B3500ul Analyser performance - carryover
B3500ul TOC analyzer has no sample-to-sample carryover. When a “dirty” 1000ppb KHP standard was analyzed no sample-to-sample carryover was recorded in the follow-up analysis of a once ultra-pure water sample.

11. To check the system pressure settings.
Check the instrument air supply pressure at the filter pack pressure regulator. The pressure should be 1.5 bar (1.2 bar if BioTector compressor is used) when the oxygen concentrator is not using any instrument air. This typically cycles from 1.5 bar to 0.9 bar when the oxygen concentrator is running.
This pressure is also shown on the O2 Controller Status menu.
Check the O2 PRESSURE SENSOR in O2 Controller Status menu. The pressure should be between 390 mbar and 400 mbar at the idle 1 l/h oxygen flow. At a 60 l/h MFC SETPOINT setting, the pressure should not be less than 320 mbar.
The BioTector B3500ul contains a number of sensors to continuously monitor system performance, and report any issues which may occur. Details in the photograph.
Using the appropriate Simulate menu, check the operation of the Mass Flow Controller (MFC) and confirm that the MFC is working at various flow set points.

12. The set point air pressure supplied from BioTector compressor should be 1.2 bar and the tube between compressor and the analyser should be as short as possible.

Pneumatic connection for air: 3/8” Nylon or PTFE tube.

13. To check the Ozone Line filter.
Salts and corrosion products can reduce ozone concentration and as a result decrease TOC recovery level.
Remove the Ozone Line Filter and wash it with DIW (or tap water). Dry the filter well and reinstall in place.

14. Replace the filter mats, check the fan.
Replace the 100mm filter mats in fan and vent housing. The fan cover is levered out from the top with a screwdriver.
Slot for screwdriver.
Filter matt.
The operation of the fan can easily be checked with the fan cover off. Note that the fan is thermostatically controlled, but can be activated from the appropriate simulation menu.
To achieve optimal efficiency of the fan filter mats should be installed according to below diagram

15. To check the BioTector B3500ul CO2 Analyzer
The BioTector B3500ul CO2 analyzer is located in the top part of the enclosure and for service it needs to be removed from the enclosure.
To remove the analyser:
- disconnect the cable,
- unscrew 4 nuts and remove the blue clamps,
Below:

CAUTION:
During service, do not remove the cover over the detector electronics, or disassemble the detector section of the CO2 analyzer.
During service, do not remove any of the CO2 absorbers on the CO2 analyzer.
Do not remove the cover over the source electronics.

16. Use gloves to reduce possible contamination
To change the diaphragm in the NF300 mixer reactor
CAUTION: A torque screwdriver with TX20 bit calibrated to 1.4Nm, or 3mm Allen bit calibrated to 1.5Nm (for pumps built with metal cover plate) is a requirement for this service operation. Do not proceed unless you have this tool.
Remove the screws on the front of the Mixer Reactor and remove the reactor motor at the back.
Reactor and Mixer viewed from the side.
Note that the reactor is independently bolted to the door panel with 4 screws from the back (2 screws visible above). These should not be removed.

Use gloves to reduce possible contamination

17. BioTector B3500ul typical site installation.

18. Initial contamination removal
Run ~10 analysis cycles to remove TOC contamination introduced during service of stoppage
Shipping and long storage can introduce TOC contamination which will affect the zero offset.
Connect DI Water or alternatively tap water to manual port and using Manual Program run 10 analysis cycles to remove the organic contamination. If the TOC results will not stabilize (within ±20ppb) run additional reactions using DIW.

19. Zero Calibration
Zero calibration carried using acid and base reagents only (default)
Using the reagent configurations from the selected range (Range 1) a zero calibration is carried out by injecting the TIC acid into the reactor, followed by the base which is then oxidized, followed by the TOC acid.
The zero offset is calculated from the result.
To neutralize the fluid in the reactor, an appropriate volume of base is injected into the reactor which neutralizes the fluid in the reactor. Note, this is not required in the normal reaction, as the volume in the reactor is much larger due to the volume of liquid injected by the sample.
The above procedure is repeated for the programmed number of zero reactions, and the zero offset calculated from the results.
When this is complete, confirm that the zero readings are stable.

20. Hach TOC standards for B3500ul system (acidified with H2SO4)
Span Calibration and Validation
TOC Standard solution for B3500ul analyzer cannot be acidified with Phosphoric acid as this could affect the pH, reduce the oxidation and introduce significant error in TOC measurement. For calibration and validation use below Hach standard solutions:
Connect the standard solution to the MANUAL/CALIBRATION port. If both of these ports are not available, use the SAMPLE 1 port, but first set the Sample Pump REVERSE time to 0 (zero) seconds in Sample Pump menu. It is recommended that the standard solution is located at the same height as the sample chamber or catch-pot.
Run the Span Calibration (or Span Check for validation) cycle using the “RUN SPAN CALIBRATION (or RUN SPAN CHECK)” function in Span Calibration menu. A minimum of 5 span calibration reactions is recommended

KHP 5mgC/l ( ) - for calibration
KHP 1mgC/l ( ) – for validation

21. Service Zero
To ensure that the correct zero offset is applied and to eliminate any remaining TOC contamination from the analyzer, a Service Zero cycle should be initiated using the SET SERVICE ZERO function in the Service menu.
When initiated, BioTector automatically runs a total of 10 zero calibration cycles during the following 500 online measurements and automatically adjusts the zero offset values to compensate for the removal of the contamination. It will therefore not be necessary to revisit the BioTector after the start-up or to repeat the Zero Calibration cycle manually. See Section Service in the User manual for further details.
Inform the client that the analyser will automatically correct the zero offset during approximately 48h and elevated result of 20-50ppb as the system expels contaminants are expected.

22. B3500ul analyser start-up sequence during commissioning and PM.1
Sequence:
10 DIW reactions (point 1 on the chart) – removal of the main portion of TOC contamination,
Zero calibration (point 2 on the chart) – initial zero offset adjustment to minimalize error during span calibration
5ppm Span calibration (point 3 on the chart, outside scale) – calibration factor adjustment
Service Zero (points 4 on the chart) – final removal of remaining TOC contamination and background adjustment (total of 10 zero calibration cycles during the following 500 online measurements).
Inform the client that the analyser will automatically correct the background during approximately 48h and elevated result of 20-50ppb as the system expels contaminants.
