Potassium Iodate Starch Paper

For the rapid detection of sulphite and sulphur dioxide.  This paper is used in food analysing laboratories.

Sulphurous acid or sulphites reduce potassium iodate to free iodine.  With starch, iodine gives a characteristic blue-black colour.  For a detection of sulphite with high sensitivity we recommend sulphite test paper (90763).

QUANTOFIX Sulfite Test Strips

For the fast and reliable determination of sulfite in solutions. The easy dip and read procedure provides a reliable result within 20 seconds.

In process and boiler water sulfite is used as an oxygen scavenger. To avoid overdosage, the concentration needs to be controlled regularly. These tests are also used to control the sulfite concentration in foodstuff treated with sulfur compounds (SO2, HSO3 –, SO32–) for a longer shelf-life. In the process of wine making the control of sulfite is important to monitor production and quality of the wine.


Directions for use

Dip QUANTOFIX Sulfite strip into the sample (pH 6-9) for 1 second.  Shake off excess liquid.  Wait 20 seconds.  Compare the test field with the colour scale.

Store QUANTOFIX Sulfite in a cool, dry place.  Avoid exposure to sunlight and moisture.
