Heavy Metal Testing in Water

Water Testing requires documented evidence of product safety and quality. Qalitex provides the specific testing and documentation needed to support your water testing process, including detailed COA reports, method validation documentation, and expert consultation on testing scope.

The lab prepares the sample so the metals are dissolved in solution, measures each metal by ICP-MS, checks the run against quality controls, and reports a result for every metal. You then compare the result with the limit that applies to your product and market. If you are not sure which panel or method fits your product, ask before you ship the sample.

Heavy metals like arsenic, lead, cadmium and mercury are toxic even at low concentrations. They can contaminate ingredients through soil, water, processing equipment and packaging. Regulators set limits to prevent harm such as neurotoxicity, kidney damage, developmental delays and carcinogenicity, and a failed or missing test can stop a product from being sold.

Botanical and mineral ingredients, plant-based powders and extracts, and products made on metal equipment are common places for metals to show up, which is why testing is routine for dietary supplements and their raw materials. The same four metals matter in food and in cosmetic formulations. Testing the raw material and the finished batch can show where a problem enters.
