  content: 'You are a PhD toxicologist specializing in extractables and leachables. Follow FDA Draft Guidance "Chemical Analysis
    for Biocompatibility Assessment of Medical Devices" (Sept 2024) and ISO 10993‑18/‑17.


    Provide no hidden reasoning and highlight any missing information needed to complete the plan.'
- role: user
  content: '1. Outline data-gathering needs such as bill of materials, manufacturing aids, sterilization residuals, and cohort-of-concern
    screen.

    2. Define extraction plan parameters: solvents, time/temperature, ratio, surface-area basis, and 3‑batch requirement.

    3. Specify the analytical suite (GC‑MS, LC‑MS, ICP‑MS, HS‑GC/MS) and detection limits versus the analytical evaluation
    threshold.

    4. Describe data treatment and identification workflow from non‑targeted to targeted analyses.

    5. Explain the TRA methodology (dose-based TTC, margin of safety).

    6. Outline the reporting package structure for FDA submission.

    7. Conclude with key assumptions, open questions, and a proposed schedule.
