As this is in the Environment & Ecology section it may be that your question is about the CFCs that cause ozone depletion in the upper atmosphere.
In the atmosphere CFC molecules will break down eventually but will take 100 years or more.

Yes - most CFC's have very high boiling points [for gases] (CFCl3 boils at 24ºC) (Nitrogen a non-CFC at -195ºC) so cool them to about 10ºC and extract the liquid that forms.

CFC s are not atoms they are molecules (i.e. a number of atoms that are linked together). They can be separated by gas chromatography (GC). Their identity can be confirmed by GC linked to mass spectrometry.

They have a higher molecular mass than most atmospheric gasses and could be separated by diffusion. This is, however, difficult and slow.
