Fig. seven reveals an overlay of both the sample UV spectra as well as the typical UV spectra for peak B when detected at 310 nm. The UV spectra from the compounds detected while in the cosmetics are instructed to generally be exactly the same compounds because the common substance because the two U

Methanol, for instance, absorbs at wavelengths underneath 205 nm, and water underneath a hundred ninety nm. When you were being employing a methanol-h2o combination as being the solvent, you would hence really have to utilize a wavelength better than 205 nm to stop false readings within the solvent.
