“…developed a number of useful devices for the flask combustion including a demountable sample carrier. Debal and Levy (65) concluded a comparative and critical study of methods for the determination of halogens in organic compounds. The use of the oxy-hydrogen flame was not recommended, but both empty-tube and closed-flask combustion techniques were suitable, with the former preferred for iodine-containing compounds when nitrogen, sulfur, phosphorus, or fluorine were also present in the compound.…”
