The formula to calculate the Peak Area is:
\[ PA = h \cdot w_{1/2} \]
Where:
Peak area is a measure used in various scientific fields, such as chromatography, to quantify the area under a peak in a graph. It is calculated by multiplying the height of the peak by its width at half-height.
Let's say you have a peak with a height (h) of 10 units and a width at half-height (w1/2) of 5 units. Using the formula:
\[ PA = 10 \cdot 5 = 50 \]
So, the peak area (PA) would be 50 units.
