Article Correctness Is Author's Responsibility: Instrument may enable mail-in testing to detect heavy metals in water

(Massachusetts Institute of Technology) MIT researchers have developed an approach called SEPSTAT, for solid-phase extraction, preservation, storage, transportation, and analysis of trace contaminants. The method is based on a small, user-friendly device the team developed, which absorbs trace contaminants in water and preserves them in a dry state so the samples can be easily dropped in the mail and shipped to a laboratory for further analysis.
