The HI84533-62 is a 30 mL bottle of pH adjustment reagent that is used for the determination of formol number in wines and fruit juices. The HI84533-62 pH adjustment reagent is required for analysis because it raises the pH of the sample prior to titration. The adjustment with this alkaline solution ensures the sample is at the correct pH before addition of formol base reagent and subsequent titration. The content of amino acids and other nitrogen compounds in wine or fruit juice is determined by an acid base titration to a fixed pH endpoint and expressed as total assimilable nitrogen. The determination of formol number is possible only after neutralization of the titratable acids present by a pH adjustment with HI84533-62 reagent, followed by the blockage of the amino groups by reaction with the HI84533-61 formol base reagent. The titration is then performed with the HI84533-50 titrant solution.

The HI84500-61 alkaline reagent is necessary for the analysis of total sulfur dioxide. The alkaline reagent raises the pH and liberates bound sulfur dioxide. This pH adjustment ensures that all of the free and bound sulfur dioxide is accounted for to give an accurate measurement of total sulfur dioxide.
