There is no consensus on the subject, hence no mention of quantity (other than for oxygenated components known to be products of combustion) in the voluntary consensus standard. Some chemists do not even know their detection limit and state that they don't have to, since fire debris analysis is a "qualitative" exercise. It is actually semi-quantitative, because the relative concentrations of individual components are what determines what a chromatographic pattern looks like.
