The formol base reagent is used to ensure adequate reaction with amino acids and nitrogen compounds present in wine or fruit juice samples. This reaction frees hydrogen ions in an amount proportional to the available nitrogen, which the titrant neutralizes to provide an accurate determination of total assimilable nitrogen.

Details
The HI84533-61 is a 230 mL bottle of formol base reagent that is used for the determination of formol number in wines and fruit juices.
The HI84533-61 formol base reagent is required for analysis because it reacts with the amino acids and nitrogenous compounds in the sample. This reaction frees hydrogen ions in an amount proportional to the available nitrogen. The titration neutralizes the free hydrogen ions and provides an accurate determination of total assimilable nitrogen.
