(2) fluorescence is a zero background technique so is orders of magnitude more sensitive that absorption which is a difference measurement. You can easily find the fluoresce and absorption spectra online. | |

Sep 12, 2023 at 15:28 | comment | added | ACR | Not possible to assign "a random" fluorescence due to salicylic acid in an unlikely sample- seawater. There are millions of other natural and unnatural compounds which can fluoresce under UV. Point # 1: Not possible, 2. Again not possible. You first need to ensure your compound is salicylic acid from seawater from an another detector like mass spectrometer. | |
