CALCULATIONS:
13. Determine the mass, μg (corrected for DE) of analyte found in the sample front (W f) and back (W b)
sorbent sections, and in the average media blank front (Bf) and back (Bb) sorbent sections.
NOTE: If W b > W f/10, report breakthrough and possible sample loss.
14. Calculate concentration, C, of analyte in the air volume sampled, V (L):
