Fig. 7 displays an overlay of the two the sample UV spectra and also the regular UV spectra for peak B when detected at 310 nm. The UV spectra of your compounds detected from the cosmetics are prompt for being the identical compounds because the regular substance as the two UV spectra coincide. Using PDA detectors can attain a UV spectrum, permitting For additional dependable qualitative analysis.
I would love to sign up for newsletters from Sartorius (Sartorius AG and its affiliated providers) based of my private passions.
