The Potassium Test (this product, MQuant®) is a semi-quantitative test strip method suitable for testing potassium in drinking water, mineral water, industrial water, wastewater, soil samples, and can be adapted for beer and fruit juices, as well as hard foods and fruits. To use, dip the test strip in a solution of the sample and compare the color to a reference card. An aqueous extract of the sample should be prepared for testing.

General description
Method: Colorimetric with test strips and reagent, 250 - 450 - 700 - 1000 - 1500 mg/L Potassium, MQuant®
The MQuant® Potassium test includes test strips and all necessary additional reagents and is used to determine the potassium content of drinking water, mineral water, industrial water and waste water, soil samples, wine, beer and fruit juices. Potassium ions react with dipicrylamine to form an orange-colored complex. The potassium concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the potassium concentration and a possible dilution factor prior to using a quantitative method such as a Reflectoquant® or Spectroquant® Potassium test.
Design for sustainability benefits:
We continue to demonstrate our commitment to our planet and a sustainable future by exploring ways to improve existing products in our portfolio. We have recently reviewed the current line of MQuant® test strips to identify key opportunities to minimize impact without compromising on the product performance.

How can I test potassium in hard food,fruits and beer. What is the test

Can solution be poured onto the test strips rather than the strips being dipped into a test solution?
1 answer-
No, this will affect the contact time, and the strips are not tested in this manner. It will lead to erroneous results. For best results, the strips should be dipped into the solution for approximately 1 second before proceeding to the next step.
