In this experiment, several device designs were employed, as well as different mixtures of a combined reagent to find which of each worked best for phosphorous detection. With the final combined reagent, the 2-channel design with narrower, 2.5-mm channel widths showed the best results, and a cleaner meeting of the two solutions. This worked fine with the most concentrated 10 ppm phosphorous, and also well with the 1.3 ppm, however the more concentrated showed better results, as would be expected. […]
