This standard outlines the process of extracting lead (Pb) using ultrasonication, heat, and nitric acid from a composite sample comprising up to four individual wipe samples of settled dust, collected from equally-sized areas within the same space.
- Usage: Prepare up to four wipe samples from equal areas in the same space for lead content determination
- Wipe Requirement: Use wipes meeting Specification E1792; do not use otherwise
- Capability: Prepares samples for lead bound within paint dust
- Limitations: May not prepare samples for lead bound within silica, silicate matrices, or non-nitric acid soluble matrices
- Adjustment Needed: Final extract solution's nitric acid concentration or strength may require adjustment for instrumental analysis compatibility
- Validation Required: User must validate this practice before using it for client samples
- Validation Note: Each wipe combination (two, three, or four wipes) forms a unique matrix and requires separate validation
