Nonetheless, TFA is often hugely powerful in strengthening retention of analytes such as carboxylic acids, in apps making use of other detectors for instance UV-VIS, because it is a reasonably potent organic and natural acid. The effects of acids and buffers range by application but normally improve chromatographic resolution when managing ionizabl
