Fig. seven exhibits an overlay of both equally the sample UV spectra along with the common UV spectra for peak B when detected at 310 nm. The UV spectra of your compounds detected from the cosmetics are recommended for being the exact same compounds given that the common compound since the two UV spectra coincide. Using PDA detectors can obtain a UV spectrum, letting for more trusted qualitative Evaluation.
The dynamic variety of the detector refers back to the array of concentrations more than which it could possibly detect analytes. A broad dynamic vary is needed for apps during which the concentrations of the analyte fluctuate extensively.
