Does the flow require certain rate? Can one just buy any air sampling device? Is it easy to b...

Check with the individual sampling tubes for airflow requirements.
Most manufacturers also sell hand pumps, that can be used to sample the air relatively inexpensively.
If you want to measure flow, in gc, we used bubble flow meters. These are easy, cheap, and relatively accurate. They take a stopwatch and calibrated volume.

Can't help you with the pump mechanism.

I know @mathew did some work a number of years ago exploring air flow. Here's a link to some of that material: https://publiclab.org/notes/mathew/07-10-2015/my-diy-formaldehyde-test-kit
