Notes

Immediately after sampling, separate the two sampling tubes to prevent post-sampling migration.

Request any (up to two (2)) of these analytes together.

Results for unrequested analytes in this group will be reported if significant amounts are found.

There is no need to contact SLTC before sampling.

*If this is your primary analyte of interest, sample for 60 min at 0.05 L/min (3L). If the relative humidity is >50% at 25°C, you can sample for 100 min at 0.05 L/min (5L).
