WebThe lower flow personal sampling pumps generally provide a flow rate of 20 cubic centimeters/minute (cc/min) to 4 L/min. These pumps are usually battery powered. High flow pumps are utilized when flow rates between 2 L/min to 20 L/min are required. High flow pumps are used for short sampling periods so as to obtain the desired sample volume. 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.
