Trifluoroacetic acid as additive on the mobile section is broadly utilized for elaborate mixtures of biomedical samples, typically peptides and proteins, making use of mostly a UV primarily based detectors. They can be employed rarely Utilized in mass spectrometry methods, on account of its residues it could leave from the detector and solvent ship
A further prevalent group of HPLC detectors are All those according to electrochemical measurements such as amperometry, voltammetry, coulometry, and conductivity. Figure twelve.49, for instance, reveals an amperometric movement cell. Effluent with the column passes in excess of the Doing work electrode, that's held at a constant potential—relati
