- •
Shipping cassettes loaded with crystalline silica did not appear to significantly affect the results.
- •
Muffle furnace sample preparation had lower recoveries than plasma ashing sample preparation.
- •
The recoveries from muffle furnace ashing are affected by the level of effort expended in scraping the crucibles.
- •
The data are suggestive of areas of the analytical process that OSHA should further investigate for improvement.
