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 allow the quick and easy determination of ammonium in solutions. The test strips come with all necessary reagents so that the measurement can be started immediately. Within 10 seconds one gets a reliable result.
Naturally, Ammonium results from the biological decay from plant and animal matter. High concentrations can be found in rural, farming areas where fertilizers are regularly used. Also, industrial effluents may contain ammonium in high levels. Depending on the pH, however, part of the ammonium is transformed to the aggressive NH₃⁻ gas, which is poisonous for aquatic life. Ammonium itself is relatively harmless. Ammonium levels >1 mg/L are not suitable for fish.
As an indicator for decomposition of animal or vegetable substances, control of Ammonium is also important for the water supply. With QUANTOFIX® Ammonium test strips the determination of Ammonium is easy, quick and reliable.
