Details
The HI84100 mini titrator is designed to determine free and total sulfur dioxide levels in wine by potentiometric titration. The HI3148B ORP electrode is used to detect the endpoint. The HI84100 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.
The HI84100 Sulfur Dioxide Mini Titrator determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:
IO3- + 5I- + 6H+ → 3I2 + 3H2O
The iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:
H2SO3 + I2 → H2SO4+ 2HIReplacement reagents required to operate the HI84100 include:
Titrant solution
HI84100-50
Alkaline reagent for total SO2
