About Analyser Solution Reagent 2 for ABB 8232
This product is sold with a 6.75-6.85% w/v NaOH content and was developed to be used in the ABB’s model 8232 to detect ammonia levels in water. The equipment uses an ion-selective probe, which contains a pH electrode and a reference electrode. The two electrodes are combined to measure pH through an internal container with a ammonia solution. More specifically, the container has a 0.1M ammonium chloride solution saturated with silver chloride, which remains separated from the sample to analyse via a gas-permeable membrane.
To conduct the analysis, the sample is forced to go through the membrane until partial pressures of ammonia equilibrate, transferring a certain amount of gas across the membrane. The resultant change in pH is measured by the pH electrode which correlates to the amount of ammonia present in the original sample.
Process needs two reagents
The equipment needs two different reagents, typically known as reagent 1 and reagent 2.
- Reagent 1: Laboratory-grade di-sodium EDTA solution. If the monitor is used in industrial applications this reagent may not be necessary as there is a negligible hardness in the sample (EDTA is used to prevent precipitation due to high hardness)
- Reagent 2: Analytical-grade Sodium Hydroxide (NaOH) solution. This is a highly caustic solution and contact with skin and eyes should be avoided.
