Description

The HI84500-55 is a 120 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84500 in determining the exact concentration of sulfur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced.

  • Standardized solution
  • Clearly marked expiration date and lot number
  • Air tight bottle with tamper-proof seal to ensure quality
Analysis of sulfur dioxide in wine, as performed on the HI84500 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is performed with HI84500-55 pump calibration solution. The pump calibration procedure involves the analysis of a known volume of a known solution. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or ORP electrode is replaced. Periodic calibrations should be performed in order to accurately determine the free and total sulfur dioxide levels in wine. 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 SO2 High Range - 30 to 400 ppm SO2
