Review on 💦 Comprehensive Water Quality Analysis: ICP 33-Elemental Test Kit - Single Sample Kit by Anna Ingrassia

Please note that none of the reviewers know if their results are correct. They just THINK they are. I created a calibration solution containing about ten different items to measure. This is easy if you know how to measure and dilute various chemical salts from larger stock solutions. I was able to verify that the levels of the elements in this solution were accurate (math guarantees accuracy anyway) using simple hobby test kits. Within a few weeks I sent three separate tests of this standard solution. None of the test results came even close to the known levels of the elements in the calibration solution (deviating by orders of magnitude), and worse, the results from the three tests were not even close. the same container. It just shows how people can convince themselves that something is good without checking their assumptions. If you are inclined to use this product, at least make sure that the results you are getting are real.
