Standard curves were constructed by measuring the peak area ratio relative to
the concentration ratio of alcohols to isoamyl alcohol in a series of five standards
. Results confirmed a linear response ( RP > 0 . 99 ; see Table 4 . 1 ) .

Peak areas for 1 - heptanol were very small due to its hydrophobic nature . This
resulted in peak area ratios relative to isoamyl alcohol near 0 . 04 . Data close to
the intercept is unduly affected by the y - intercept factor in the regression ...
