This project aims to find the area under the curves from the graph obtained performing High Performance Liquid Chromatography. This will be used done by using the given function of the line and doing a defined integral between two points of the curve. The purpose of this is to find the concentration of a set of compounds found in a solution, with each peak representing a different element present in the sample. The bigger and longest the curve, the higher the area of the peak and the stronger the concentration of the element.
