The HI38049-100 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate ammonia measurements with the HI38049 chemical test kit. These reagents follow the Nessler method to determine fresh water ammonia concentration as ammonia-nitrogen (NH3-N).
For determination of ammonia, the Nessler reagent is added to the sample under alkaline conditions to react with ammonia. The reaction between ammonia and the mercury-containing reagent causes a yellow colored complex to form; the greater the concentration, the deeper the color. A Checker disc is included for an accurate, side-by-side, visual analysis to determine ammonia concentration. These reagents are designed to be used with samples that have an expected ammonia range of 0.0 to 3.0 mg/L (ppm) NH3-N.
