The results obtained by calculating the percentage of nicotine lost 
from each sample and averaging for the three strengths are shown 
in Figures 1 to 10. The figures, therefore, show the percentage of 
nicotine lost from the samples, while the tables show the percentage 
of nicotine in the samples at the time of analysis.
