Gate 1: Analytical Validation & Lab Audits
For high-risk categories (water filters, air purifiers, cookware), we prioritize products with verifiable test reports from ISO 17025 accredited laboratories. We look for specific analytical methods:
- Heavy Metal Analysis: Using ICP-MS to detect Lead, Arsenic, Cadmium, and Mercury with detection limits reaching parts-per-billion (ppb) or lower.
- Organic Contaminant Profiling: Utilizing LC-MS/MS for the detection of "Forever Chemicals" (PFAS), pesticides, and VOCs.
- Physical Performance Metrics: Measuring Clean Air Delivery Rate (CADR) for purifiers and filtration efficiency curves for water filters across different flow rates.
