-
Obtain the correct pump, operating instructions, media holder, inlet device (where used) flow-measuring device, and media for your application.
-
Look up the analytes in the sampling guide. Note the Flow rate and volume ranges for each compound of interest.
-
Select the rate and volume that meet your needs, e.g. lower rates = longer
sampling time to a given volume. Flow rate (lpm) x Time (min) = Volume (L).
-
Compounds with the same compatibility code can be analyzed together, though the flow rates and volumes must be compatible also.
-
Open and insert media into the appropriate holder or sampling device. Sorbent tube arrow points to pump, cassette goes inlet end down in the cassette holder.
-
Start pump and connect flow-measuring device. Adjust the flow rate as desired, write it down, remove the flow-measuring device, and place the pump in the sampling area.
-
Check the flow periodically, and check for signs of overloading. At the conclusion of the sampling period, reconnect the flow-measuring device, and write down the flow.
-
Turn off pump, remove media from holder, and close (cap it). Complete the Chain of Custody and ship to EMSL following sample handling instructions from the method.
