I was making stress degradation studies on a drug and I injected the drug with its degradation products . I selected the ''Select peak purity " from spectrum menu. A figure appeared with a calculated peak purity factor for the peak of interest. The problem was that the purity threshold is labelled as ''set by user'' .I want it to be calculated and I do not know why . I attached a picture from the software to explain the necessary steps to get purity threshold calculated. If anyone could help me to get through these steps
