The HI-3850 Ascorbic acid test kit has been specifically designed for the determination of the content in Vitamin V of beverages and is based on drop-count titration. Ascorbic Acid (Vitamin C) is used in the food and beverage industry as a supplement in fruit juice, as well as its flavour and preservative qualities.

HI-3850 การใช้งาน
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
Fill the graduated plastic test tube up to the 10 mL mark with the sample and pour it in the calibrated vessel. Add deionized water up to the 50 mL mark to dilute. Similarly prepare another sample using theother calibrated vessel and keep it as a reference for the initial color.
Using the plastic dropper add 1 mL of HI 3850A-0 reagent to one sample only. Swirl to mix.
Add 4 drops of Starch Indicator and swirl to mix.
Add drops of HI 3850C-0 reagent, while swirling and counting the drops, until a persistent blue color is developed. Compare the solution to the unreacted sample to be sure of the color change.
Count the drops needed to obtain the color change. To calculate the concentration of Ascorbic Acid multiply by 10 the number of drops of HI 3850C-0 titration reagent used: # of DROPS * 10 = ppm C6 H8 O6
