Well, I recall in a childrens’ book, The Case of the Bashful Bank Robber by Hildick (don’t remember the first name…it’s a McGurk mystery), one of the characters came up with a system for quantifying smell, separating it into “Sulfas” (since sulfur is the main element in most bad smells) and “Sucras” (for sweet smells, but I don’t know what the active element would be).
Perhaps there’s some scientific validity to that…there are only a few elements our noses actually detect, and the range of scents are combinations of them.

“Sherlock Holmes once said that once you have eliminated the
impossible, whatever remains, however improbable, must be
the answer. I, however, do not like to eliminate the impossible.
The impossible often has a kind of integrity to it that the merely improbable lacks.”
