关于这个问题，Paul C. Sadek所著的The HPLC Solvent Guide 2nd Edition（论坛上发过这篇资料）中所解释，在第75页，我摘录一段
Neat ethanol has found limited use, not because it does not offer interesting and useful chromatographic properties, but because of the artificially high cost due to strict government control over its use and dispensation. Denatured ethanol, commonly called reagent alcohol, is readily available in many forms. However, only those with either a hydrocarbon at ~1% levels or ones containing methanol/IPA mixes at the 1-5% level are compatible with UV work. Note that the potential variability in the level of added denaturant poses potential reproducibility problems for the chromatographer.
