At the conclusion of the sampling period of time, the openings around the ends with the cassette are sealed having a plug plus the cassette is sent to your laboratory for Investigation. When sampling with sorbent tubes and filters, the laboratory has to be supplied with the volume of air sampled which is decided from your small charge on the pump regarded from calibration and the duration on the sampling period. Calculations for this willpower will probably be discussed in the subsequent installment of this series.
