This is a single ICP Mass Spectrometry test for salt water. If you need a fresh water test please purchase our freshwater ICP Mass Spec test. We test for over 50 elements and provide a dosing calculator for trace elements. Our methods are over 1000x more accurate and effective than traditional solutions. Standard water test kits can miss critical toxins in your water, but ICP tests for more elements with a higher degree of accuracy. We inject your water sample into a 10,000-degree plasma chamber. It splits the water into its component elements, which we can detect up to one part per trillion — giving you unrivaled precision in your results.
