In the body of the form, for each sample, include the following information:
- Date sample collected
- Sample medium (e.g., glass fiber filter, Orbo 70 tube)
- Sample number
- Substance(s) to be analyzed for
- Sample volume
- Potentially interfering compounds present in area of sampling
Leave the amount of analyte, concentration of the analyte, and analytical method columns blank.
If different samples are submitted for separate analyses, please fill out a separate sheet for each analyte. The exception is when there is more than one analyte per sample, for example ethinyl estradiol and norethindrone on the same filter; in this case use the same sheet for such samples.
Blanks must also have a sample number and be listed on the form.
