WL: Whole layer; BB: Blackish brown; YO: Yellowish orange;
(1) Amines stain layer 1 similarly to Ammonia.
(2) Olefins stain layer 6 similarly to Carbon Monoxide.
(3) (Inlet) means the approximate gas concentration discolor the inlet of the layer.
(4) (Whole layer) means the approximate gas concentration discolor the reagent of the layer.
