Composition of the 5 mixtures. Columns from left to right: mixture type, odorant names, odorant CAS numbers, mixture composition at 5 concentration ratios (denoted by the approximated percentages of the components in the mixture, numbered as 1 or 2). For each mixture, the separated constituents were diluted with clean air to the overall flow of the mixture and tested for their pleasantness and intensity, as detailed in the text.
