Descripción
These high quality reagents are designed to follow the chromotropic acid method for colorimetric determination of total nitrogen, in which a digestion is required to convert all forms of nitrogen to nitrate. Sodium metabisulfite is added to remove potential interferences. The reaction between nitrate and the reagents causes a yellow tint in the sample, and a compatible meter can be used to determine the concentration from the color that is produced.
- Reagent sets are available for low range or high range determinations
- Pre-made, pre-measured water testing reagents for ease of use
- Prepared with high purity chemicals manufactured in Hanna's state-of-the-art facility
- Clearly marked with expiration date and lot number on each packet and bottle for traceability
