Web3 mrt. 2024 · A simple computation for estimation of the peak area can be stated as area (a) is equal to the height of the peak (h) times the width measurement at half height (w). If we would manually measure a small peak by enlarging it, we should also enlarge the others at the same factor so we can still compute for their relative areas. Web14 jul. 2024 · To do this, use a ruler to measure the difference between the top and the bottom of each of the integration curves. After you measure the height of each peak on the spectrum, divide each of the heights by the smallest height. This will give you the ratios. In this example, the smallest height is 17 mm, so you divide both heights by 17 mm. pytest setup class
