Figure Lengend Snippet: Carbon (A) and oxygen (B) content analyses of positive control material coal from the open-air coal terminal in Curtis Bay, Baltimore, Maryland, USA on conductive carbon tape. Particle size (longest visible dimension >5 μm) and elemental compositional (carbon ≥75 At.% and oxygen ≤20 At.%) limits shown by red lines bounding the yellow bow of accepted coal composition and size for the coal dust classification criteria. Red circles represent analyses of the carbon tape substrate. Note . At.% = atomic weight percent. C = carbon. O = oxygen.
