Fig. 7 displays an overlay of both equally the sample UV spectra as well as conventional UV spectra for peak B when detected at 310 nm. The UV spectra with the compounds detected during the cosmetics are proposed to get precisely the same compounds since the common material as the two UV spectra coincide. The usage of PDA detectors can get hold of … Read More
