    • A fluid storage and dispensing system including a vessel containing a low heel carbon sorbent having fluid adsorbed thereon, with the system arranged to effect desorption of the fluid from the sorbent for dispensing of fluid on demand. The low heel carbon sorbent preferably is characterized by at least one of the following characteristics: (i) Heel, measured for gaseous arsine (AsH3) at 20° C. at 20 Torr, of not more than 50 grams AsH3 per liter of bed of the sorbent material; (ii) Heel, measured for gaseous boron trifluoride (BF3) at 20° C. at 20 Torr, of not more than 20 grams boron trifloride per liter of bed of the sorbent material; (iii) Heel, measured for gaseous germanium tetrafluoride (GeF4) at 20° C. at 20 Torr, of not more than 250 grams AsH3 per liter of bed of the sorbent material; (iv) Heel, measured for gaseous arsenic pentafluoride (AsF5) at 20° C. at 20 Torr, of not more than 700 grams AsF5 per liter of bed of the sorbent material; (v) Heel, measured for gaseous trimethyl silane (3MS) at 20° C. at 20 Torr, of not more than 160 grams 3MS per liter of bed of the sorbent material; and (vi) Heel, measured for gaseous ethane (C2H4) at 21° C. at 25 Torr, of not more than 10 grams ethane per liter of bed of the sorbent material.
