The Plasma-AL concentrations can be determined by simple titration tests.
• Restore the bath volume with water and mix well.
• Pipette 1.0 ml of the bath sample into a conical flask.
• Add approximately 100 ml. Distilled water
• Add 5 drops of Bromocresol green indicator.
• Titrate with 0.1N NaOH contained in a burette, until the end point greencolour appears
• The burette reading is the Pointage of bath.
