The HI84500-62 stabilizer powder packets are necessary to convert the iodate titrant into iodine. The iodine then reacts with sulfur dioxide and the HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges.

The HI84500-62 stabilizer powder packets are necessary to convert the iodate titrant into iodine. The iodine then reacts with sulfur dioxide and the HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges. The decision by Hanna to use the HI84500-62 stabilizer powder packets and iodate titrant in place of a iodine titrant is due to shelf stability. Iodate offers much greater shelf stability than iodine. By using stabilizer packets the titrant solutions remain stable for longer periods of time.The HI84500 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 HI84500 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 + 2HI Replacement reagents required to operate the HI84500 include: Low Range - 1.0 to 40.0 ppm of SO2 High Range - 30 to 400 ppm of SO2 Pump calibration standard HI84500-55 HI84500-55 Titrant solution HI84500-50 HI84500-51 Acid reagent HI84500-60 HI84500-60 Alkaline reagent (Total SO2)

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.
