Sulfur dioxide is used as a preservative in wine and there are restrictions limiting the amount that can
be added in most wine producing countries. This test kit is a fast and easy way to determine the
amount of total sulfur dioxide in wine samples, without the need for the laborious setup associated with
For this Test Kit semi-micro cuvettes are required.
PRINCIPLE OF MEASUREMENT
The amount of sulfite present in wine is measured by monitoring the reaction with a chromogen under
basic conditions. The reduction of the chromogen leads to formation of a strongly absorbing
compound which can be measured at 340 nm. The measured amount of the activated chromogen is
stoichiometrically proportional to the amount of total sulphite present.
ITEMS REQUIRED BUT NOT SUPPLIED
Distilled water 1W002
Spectrophotometer 2S120 or 2S140
Semi-micro cuvettes 2C890
