Testing

Overview

Stub. This section is a planned home for analytical-method, detection-limit, and laboratory-program reference content. Pages here will support the wiki’s occurrence-data claims by documenting what analytical confidence those numbers actually carry.

Planned topics:

• ICP-MS — Inductively coupled plasma mass spectrometry — Inductively coupled plasma mass spectrometry, the dominant trace-metal analytical method underlying nearly all post-2000 food-occurrence datasets cited in this wiki.
• EN 1811 Nickel Release Testing — nickel release from skin-contact articles and piercing post assemblies, reported as µg/cm2/week rather than food ppb.
• HPLC-ICP-MS arsenic speciation methods (separating iAs from organic As species) — covered as a hyphenated configuration on the ICP-MS page; a dedicated speciation page is planned.
• AOAC and EPA validated methods commonly cited in regulatory documents.
• Round-robin and proficiency-testing programs (FAPAS and others) that bound inter-laboratory variability.
• Field-sampling and homogenization considerations specific to heavy-metal occurrence surveys.
• Reporting-limit conventions and the treatment of left-censored data in occurrence statistics.

External references this section will draw on:

• Jakubowski 2012 — detection-limit tables for cadmium analysis methods.
• FDA TDS 2018-2020 — FDA Total Diet Study analytical methods documentation.
• Codex CXS 193-1995 — Codex methods of analysis and sampling references for matrix-level MLs.
