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. 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

The test strips allow the quick and easy determination of arsenic in solutions. They come with all necessary reagents so that the measurement can immediately be started. Within 20 to 30 minutes one gets reliable results.

As a naturally occurring element, arsenic is widely distributed in the earth's crust. In the natural environment it is most frequently present as inorganic arsenic compound in combination with sulphur or oxygen. Organic arsenic compounds can be used as pesticides. Arsenic is toxic and causes skin diseases, keratosis and melanomas. Therefore, arsenic levels in drinking water have to be monitored thoroughly.
