Results confirmed a linear response ( RP > 0 . 99 ; see Table 4 . 1 ) . Linear
regression of the data yielded a formula to predict alcohol concentration based
on the concentration of the injection standard and the peak areas of both
standard and ...

As detailed later , this regression line was used to calculate the level of alcohols
in the aqueous phase . Peak areas for 1 - heptanol were very small due to its
hydrophobic nature . This resulted in peak area ratios relative to isoamyl alcohol
...

This point can be illustrated by comparing the entropy of two conditions . Given
that AS is negative , T283 K AS is greater ( and more favorable ) than T323 K AS .
Linear regression slopes for the alcohol series are also presented in Table 4 . 3 .
