FAQ of charcoal sorbent tubes for air sampling
What is the difference between charcoal sorbent tubes and DNPH tubes?
Charcoal sorbent tubes are used for non-polar substances such as VOCs and organic vapors, while DNPH tubes are primarily used for derivatization sampling of aldehydes and ketones.
How do I use a sampling sorbent tubes?
Connect the tube to a sampling pump and collect air samples at the specified flow rate and sampling time. After sampling, seal both ends and send the tube to the laboratory for desorption analysis.
What are the storage conditions for sorbent tubes for air sampling?
We recommend storing them sealed and protected from light in a cool, dry environment to prevent the activated carbon from getting wet or prematurely absorbing impurities from the air.
