HANNA HI 93733-01 Ammonia HR Nessler Method for Photometer 100 test

The HI93733-01 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 color 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.
