Calculating peak areas
To calculate the areas of the peaks, multiply the height of
the peak times its width at half height.
For example, using a ruler, the Peak A was measured
to have a height of 28.2 mm and a width at the half-height
of 3.5 mm. Peak B has a height of 41.2 mm and a width
at half-height of 4.5 mm. Therefore, the areas of the peaks
can be calcuated as follows:
Using these areas, the percent of each compound in the sample
can be calculated.
In addition, the ratio of B to A can be found using the areas.
