Every metal, every matrix, one bench.
Heavy-metal risk changes with the matrix (a botanical bioaccumulates, an API carries catalyst residue, water carries plumbing lead), so the analyte list and the limit both change; ICP-MS quantifies them all to ppb and we apply the regulatory ceiling that fits your product.

Where heavy-metal failures come from.
Metals rarely enter a product by accident at the fill line; they come from soil the plant grew in, catalysts in synthesis, pigments in color additives, or the plumbing water traveled through.
USP <232>/<233>, EPA 200.8, FDA Closer-to-Zero, ISO 17025 Aligned.
The metal is the same; the ceiling depends on the regulation that governs your product. Here's what we map to.
Permitted Daily Exposure limits for elemental impurities in pharmaceuticals and many supplements, by route (oral/parenteral/inhalation). We report each element against its PDE.
The validated ICP-MS/ICP-OES procedures and system-suitability, spike-recovery, and method-blank criteria that make a USP <232> result defensible.
The reference ICP-MS method for regulated drinking-water metals under the Lead & Copper Rule and Arsenic Rule, reported in µg/L against the MCL.
FDA action levels for lead, arsenic, cadmium, and mercury in foods for babies and young children — the framework driving baby-food and juice testing.
Documented digestion, calibration, LOD/LOQ per element, and spike-recovery QC; operated to ISO/IEC 17025 expectations (we do not currently hold formal ISO 17025 accreditation).
The regulated "big four" — lead, cadmium, arsenic, mercury — plus the full USP <232> elemental-impurity list (cobalt, vanadium, nickel, and the class-2/3 elements) when your route requires it. Speciated arsenic and hexavalent chromium are available for matrices where the total number overstates the toxic fraction.
