Pump Calibration Standard for Sulfur Dioxide Mini Titrator - HI84100-55

$86.02

The HI84100-55 is a 500 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84100 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 HI84100 in determining the exact concentration of sulfur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced.

*The HI84100 Sulfur Dioxide Mini Titrator has been discontinued. The new version is the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis which has its own set of reagents.

  • Standardized solution
  • Clearly marked expiration date and lot number
  • Air tight bottle with tamper-proof seal

Description

Analysis of sulfur dioxide in wine, as performed on the HI84100 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 HI84100-55 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, 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 HI84100 determines the free and total sulfur dioxide concentration in wine using the Ripper method. The HI84100 can be used in all wines, including red, which are difficult to test using traditional methods associated with a distinctive color change to determine the endpoint. Excess iodide added to the wine sample reacts with iodate introduced by the titrant to produce iodine:

IO3 + 5I + 6H+ → 3I2 + 3H2O

The iodine produced in the sample then reacts with sulfur dioxide in the wine according to the redox reaction below:

H2SO3 + I2 → H2SO4 + 2HI

Replacement reagents required to operate the HI84100 include:

Titrant solution HI84100-50
Alkaline reagent for total SO2 HI84100-51
Acid reagent for total SO2 HI84100-52
