i-DReC, a New Photodiode Array Detector Function; Impurity Analysis Application

Using the Intelligent Dynamic Range Extension Calculator (i-DReC), a new data analysis function for the photodiode array detector, peak area and peak height can be calculated using spectrum similarity, even in a high-concentration region where the detector signal is saturated. Here, we explain the principle of i-DReC, and introduce an example of analysis that applies this principle in determining the area percentage of an impurity in a pharmaceutical substance.
