Abstract
A sampling device includes a gas guiding unit having upper and lower guiding grooves and a liquid guiding unit abutting against the gas guiding unit and having a passage groove that communicates fluidly with the upper and lower guiding grooves. The liquid guiding unit includes a liquid-retaining mechanism including a liquid-retaining net that enables liquid to form a liquid membrane through capillary action. Gas introduced into the passage groove passes through the liquid membrane where airborne components contained therein are dissolved. The liquid containing the dissolved airborne components is extracted from the sampling device as a test sample.
