• Air Sampling Directions with Use of Summa Canister

Grab Sample Setup

You should have received a female MircoQT valve spring loaded assembly with your canister.
Remove black cap over the male end of the MircoQT valve located on top of the canister. Keep this black cap.
Place canister in desired location that you wish to sample. Place the female end of the MircoQT valve over the male MicroQT valve located on the top of the canister. The female MicroQT valve is spring loaded.
Place your index finger on top of the female MircoQT valve and gently put pressure on the valve. With your other hand, pull up on the spring. At this point the valve assembly should drop onto the male MicroQT (it should drop about ¼ inch).
Release the spring and your index finger. If the valve assembly has been correctly connected, you should hear a hissing noise and the canister will be filling with sample.
Allow about 1 to 2 minutes for the canister to completely fill (this time may vary depending on the size of your canister). The canister is completely full when the hissing noise has stopped.
Remove female MircoQT valve.
Replace black cap.

Follow Control Setup Directions

You should have received a sample flow controller with female MircoQT valve spring loaded assembly with your canister.
Remove black cap over the male end of the MircoQT valve located on top of the canister. Keep this black cap.
Place canister in desired location that you wish to sample. Place the flow controller over the top of the male end MicroQT valve on top of the canister so the female end of the MircoQT valve goes over the male MicroQT valve. The female MicroQT valve is spring loaded.
Remove the brass nut that is connected via a chain off of the filter. This nut will only be hand tight; you will not need a wrench.
VERY IMPORTANT
It is extremely important to sample within the time frame that you requested the sample flow rate to be set at. Collecting below or above the desired sampling time may impact our ability to test the sample while maintaining desired detections levels. As a general rule, +/- 10% of the desired sampling time is recommended.
Place your index finger on top of the “candy cane” point on the flow controller and gently apply downward pressure. With your other hand, pull up on the spring at the base of the flow controller. At this point the valve assembly should drop onto the male MicroQT (it should drop about ¼ inch).
Release the spring. Lift the flow controller placing your index and middle finger under the candy cane. If the unit has been connected correctly, the can should stay connected to the controller.
Record the gauge pressure on chain of custody. This is recorded as your initial gauge setting. The gauge should be reading -30 to -28. If not, contact lab prior to sampling.
After the sampling time has been met, record the gauge pressure again. This is recorded as your final gauge setting. The gauge should be reading -5 to -2.
Remove the flow controller by pulling up on the spring while gently pulling up on the flow controller with your index finger under the “candy cane”.
Put the black cap back on top of the male end MircoQT valve on top of the can and replace the brass nut on the bottom of the filter.
