Detergent Sample Cell Cleaning Instructions (if Sample Cell Is Dirty)
1. If the 'PPM value' OR the 'Sample Cell Condition Percentage' is out of starting
parameters, the sample cell requires chemical and mechanical cleaning prior to
operation.
2. Turn the TD‐107 Sample Cell Inlet handle to the Maintenance position (you will see an ALM flash
on the display screen).
3. Fill the cleaning syringe with 30ml of the provided cleaning solution (NAG Part
Number 2522). If the recommended cleaning solution is not available, substitute
mild detergent diluted with 50% fresh water.
4. Inject 30 ml of the cleaning fluid into the sample cell via the Luer‐Lok® fitting.
Leave the syringe attached to the Luer‐Lok® while performing the next step
5. Unscrew the sample cell cap (fitting located at the top of the sample cell)
6. Aggressively scrub the inner quartz tube of the sample cell with the provided flow
cell brush (NAG Part Number 2506) for approximately 1 minute. Note: Use of a
non‐recommended flow cell brush could potentially scratch the inner quartz tube
of the sample cell and cause the OCM to malfunction.
7. Remove the brush and screw the sample cell cap back onto the top of the
sample cell. Note: Hand‐tighten + ¼ turn for the sample cell cap. Do not over‐
tighten or use pliers or wrenches on the sample cell cap.
8. Use the cleaning syringe to draw out the cleaning fluid currently in the sample
cell. Discard the cleaning fluid.
9. Use a clean syringe to inject 50ml of clean fresh water into the sample cell.
10. On the display screen, you will see (a) Alarm, (b) PPM value, (c) Cell Temperature, (d) Cell
Condition Percentage (between 0% ‐ 100%).
11. Allow PPM value to stabilize (typically between 0‐2ppm in fresh clean water).
12. Allow the Cell Condition Percentage to stabilize (typically between 70‐100% in fresh clean water).
13. If the PPM value has stabilized between 0‐5ppm AND the Cell Condition
percentage has stabilized between 70‐100%, the unit is ready for
operation.
14. Place the sample cell valve handle into Operating position and begin OWS operations.
15. If the PPM value OR Cell Condition percentage is still out of starting parameters,
acidic cleaning is required.
Acidic Sample Cell Cleaning Instruction in Cases where Sample Cell Is Extremely Fouled
1. Turn the TD‐107 Sample Cell Inlet handle to the Maintenance position (you will see an ALM flash
on the display screen).
2. Unscrew the sample cell cap (fitting located at the top of the sample cell).
3. Dip the provided flow cell cleaning brush (NAG Part Number 2506) in 6N Hydrochloric Acid. If 6N
HCL is unavailable, muriatic acid or citric acid is an acceptable substitute.
4. Aggressively scrub the inner quartz tube of the sample cell with the acid cleaner
for approximately 1 minute. Note: Use of a non‐recommended flow cell brush
could potentially scratch the inner quartz tube of the sample cell and cause the
OCM to malfunction.
5. Remove the brush and screw the sample cell cap back onto the top of the
sample cell. Note: Hand‐tighten + ¼ turn for the sample cell cap. Do not over‐
tighten or use pliers or wrenches on the sample cell cap.
6. Use a clean syringe to inject 50ml of clean fresh water into the sample cell to flush the acid out.
