The HI-93733-01 are reagents for the colorimetric determination of ammonium (NH₄⁺). There are enough reagents for 100 tests to be used with Hanna’s compatible portable photometer. These high quality reagents are clearly marked with the lot number and expiry date on each bottle for traceability.

• Pre-made reagents for ease of use
• Prepared with high purity chemicals

The HI-93733-01 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the Nessler Method in which the reaction between ammonia and reagents causes a yellow tint in the sample. By simply adding the reagents to the sample, the reaction between ammonia and reagents causes a yellow tint in the sample will take place. The intensity of colour is determined by a compatible photometer and the concentration will be displayed. The results will be displayed in ppm (mg/L) of ammonium (NH₄⁺) but can easily be converted to ammonia-nitrogen (NH₃-N) or ammonia (NH₃). These reagents are designed to be used with samples that have an expected range of 0.0 to 50.0 ppm ammonium.
