Pick explains in Schwarte's book what is already well known, that the charcoal layer has a wide, "non-specific effect, and it retains almost all materials of which the molecular weight is not too small, even if very strongly neutral in character (as, for example, chlorpicrin)."
When the use of chlorpicrin mixtures gained in importance in 1917, the layer of charcoal was increased at the expense of the other two layers.
The compounds used in the bombs were phosgene and a mixture of phosgene and chlorpicrin.
