Description of the method for the determination of ammonium by the EZ4005 analyzer
Determination of the concentration of ammonia in water is based on acid-base titration using a pH electrode. The sample is titrated with sodium hydroxide (NaOH). After determining the end point, the ammonia concentration is calculated.
Analysis step-by-step: The analysis vessel is cleaned and filled with fresh sample. After sampling, the initial pH value is measured and corrected with sulfuric acid (H2SO4). Next, titration with sodium hydroxide (NaOH) begins. After determining the end point, the ammonia concentration is calculated.
Specifications:
- Detection limit ≤ 10 mg/l
- Interference Soap, oily substances, suspended solids or sediment can coat the glass electrode and cause a weak reaction. Allow extra time between titrant additions to equilibrate the electrode, or clean the electrodes from time to time. Alkaline compounds can interfere with titration.

EZ5000 Series Alkalinity and Hardness Analyzers
The instrument configuration "Total Hardness + Alkalinity" performs a sequence of two different titration methods: acid-base titration with a combination electrode for alkalinity determination and colorimetric titration for hardness determination in a single titration vessel. Combined measurement of two parameters in one analyzer is a convenient solution for operators and eliminates the need for additional space and the purchase of a second analyzer.
