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 Sulphate in solutions. The easy dip-and-read-procedure provides a reliable result within 2 minutes.
Sulphate is regularly found in natural waters. In cooling water and ion exchange systems it must be monitored to prevent the formation of calcium Sulphate (gypsum). The Sulphate determination is also of importance to evaluate the aggressiveness of water towards concrete. In the beverage industry it is tested because of its effect on odour and taste.
