Baker Hughes Drilling Fluids
Equipment and Reagents
1. pH/mv Meter (Orion or instrument capable of using a fluoride electrode and
having concentration mode capabilities)
2. Combination Fluoride Electrode with BNC connector - Orion 9609BN (currently
supplied with Ion plus A Optimum Results filling solution
3. Reference Electrode Filling Solution - Orion Ion plus A Optimum Results filling
solution (Orion 900061) or IONALYZER reference electrode filling solution
(Orion 900001)
4. Plastic Pipette - 0.5 ml
5. Plastic Beakers (2) - 150 ml
6. Plastic Graduated Cylinder(2) - 50 ml
7. Pipette (3 ml) or 10cc plastic syringe
8. Potassium Fluoride Solution - 0.0010 M (10 Standard)
9. Potassium Fluoride Solution - 0.010 M (100 Standard)
10. Acetic Acid/Potassium Acetate Buffer
Standards Preparation for Instrument Calibration
Note:
Graduated cylinders, beakers, and pipettes should be rinsed with distilled water and dried
between each use.
1. Pour the 30 ml of 0.0010 M Potassium Fluoride solution into a plastic beaker.
2. Deliver by pipette or 10cc plastic syringe 3 ml of the Acetic Acid/Potassium
Acetate Buffer into the plastic beaker of 0.0010 M Potassium Fluoride solution.
3. Swirl the beaker contents to ensure proper mixing. Allow the solution to sit for
five minutes.
4. Place 30 ml of 0.010 M (100 Standard) Potassium Fluoride solution into a plastic
graduated cylinder.
5. Pour the 30 ml of 0.010 M Potassium Fluoride solution into a plastic beaker.
6. Deliver by pipette or 10cc plastic syringe 3 ml of the Acetic Acid/Potassium
Acetate Buffer into the plastic beaker of 0.010 M Potassium Fluoride.
7. Swirl the beaker contents to ensure proper mixing. Allow the solution to sit for
five minutes.
