"Odours are just organic molecules" Yeah. Right. This is why Yeah. Right. This is why H2S has no smell. (in fact, some claim is has not and we smell something else). "that are detected by the cells in our noses, and it's possible to identify them with various techniques." Well, I think this was not the question. Yes, the mentioned start-up in this thread (owlstonemedical) uses a "Field Asymmetric Ion Mobility Spectrometer", might work, but I am not too impressed by the approach. Also, would not call this a detection of "scent". Would be more impressed if they really build an artificial nose that can smell. They eye has not receptors to detect dogs, chairs, cars but detects a spectrum. Same with the ear and actually, the same with the nose. The literature is out there.
