The HI84433-50 is a 100 mL bottle of alkaline titrant solution that is used for determination of formol number in wine and fruit juices.
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 HI84433-51 reagent, followed by the blockage of the amino groups by reaction with the HI84433-60 formol base reagent. The titration is then performed with the HI84433-50 titrant solution.
