A method for the determination of hydrogen
sulphide in cigarette whole smoke has been developed
which is applicable to the determination of the delivery
from one or two cigarettes. The coefficient of
variation of determined deliveries is of the order
of lo%.
Application of the method to the determination
of deliveries of hydrogen sulphide from different
tobacco blends revealed -what flue-cured tobacco
cigarettes delivered more than burley tobacco cigarettes
and less than those manufactured from fermented tobacco.
Filtration of hydrogen sulphide by conventional
cellulose acetate and Myria/cellulose acetate tips was
found to be nominal (less than 20%) while that by carbon
containing tips was found to be greater than 7Q4.
