"WebJul 28, 2003 · The volume of air sampled is obtained by multiplying the flow rate by the duration of the sampling. For example, if the pump flow rate is 2 liters per minute and we sample for 2 hours (i.e. 120 minutes), the sample volume is determined by multiplying the flow rate by the sampling time. In this case, 2 lpm x 120 minutes is 240 liters. " - Can sampling pumps be field calibrated
