“…Maly and Krsek (200) described a technique for carbon and hydrogen based on the permeability of hydrogen and oxygen gases through fused silica. Ballschmiter and Tolg(14) absorbed combustion products containing C02 in O.OlAf Ba-(OH)2 solution and determined the excess Ba42 by titration with O.OlAf EDTA. White (848) employed emptytube combustion and absorbed any C02…”
