QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. These test strips are immediately ready-to-use. They do not require additional accessories. The test strips are intended for single use, maintenance or calibration are not required.
- Results within seconds: Just dip, wait and read against multi-stage colour scale
- Always ready to use: No accessories necessary for evaluation
- Safe results: Desiccant in the stopper for optimal protection of the strips against humidity
These test strips are for the rapid and reliable determination of Sulphite in solutions. The easy dip-and-read-procedure provides a reliable result within 20 seconds.
In process and boiler water, Sulphite is used as an oxygen scavenger. To avoid over treatment, the concentration needs to be controlled, regularly. These tests are also used to control the Sulphite concentration in foodstuff treated with Sulfur compounds (SO₂, HSO₃⁻, SO₃²⁻) for longer shelf-life. In the process of wine making the control of Sulphite is important to control production and quality of the wine.
