Univariate calibrations with or without chemometric assistance for determination of drugs lacking peak maxima in their zero-order profiles.
Magdy R, Hemdan A, Fares NV, Farouk M. Magdy R, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2019 Jan 5;206:207-215. doi: 10.1016/j.saa.2018.08.007. Epub 2018 Aug 6. Spectrochim Acta A Mol Biomol Spectrosc. 2019. PMID: 30114580
Trandolapril has no sharp peak in its zero-order spectrum and therefore, it is difficult to be measured by direct spectrophotometry. ...The first method for measuring Trandolapril is Constant Multiplication-Spectrum Subtraction (CM-SS), where Trandolapril was …
