O A calibration curve must be constructed for accurate quantitative chemical analyis. A calibration curve is a graph of detector's response versus analyte concentration. O To construct a calibration curve, one has to prepare a series of analyte's standard solutions and measure the intensity of their detector's response (p A less steap calibration curve (smaller slope) indicates better sensitivity for the analytical method compared to the more steap (bigger slope) curve.
