* All Reporting Limits are for an 8 hour sampling when the analysis is performed at AT Labs.

** The sampling rates were changed starting with lot 8M10, which expires 8/31/11.

Use the Old Sampling Rates for any badge expiring before 8/31/11.
Use the New Sampling Rates for any badge expiring on or after 8/30/11.

Chemicals listed without a reporting limit nor Method Reference have not been validated by AT Labs. The sampling rates were calculated at another lab's request. While the 571 badge most likely works for these chemicals, Assay Technology has not generated any validation data that proves that it does.
