Normally, activated carbons (R 1) are made in particulate form as powders or fine granules less than 1.0 mm in size with an average diameter between 0.15 and 0.25 mm. Thus they present a large surface to volume ratio with a small diffusion distance. [clarifiion needed] Activated carbon (R 1) is defined as the activated carbon particles retained on a 50-mesh sieve (0.297 mm).
