What kind of sampling precedes detection?
Sampling of large volumes of air and enrichment on suitable filters precedes the dection of the analytes of interest.
I have a dataset with about 80 different species. As usual, some species are very easy to identify with certainty whereas others are more difficult, which means that I am less certain of my...
