For characterizing keto acids, paper chromatography of their DNPHa is most widely used irrespective of the disadvantages (1)) some of which are as follows: According to the methods reported before 1962, the DNPH formed by the usual method were extracted from water solution with an organic solvent su
## Abstract The separation of the toxicologically important aldehyde acrolein from other carbonyl compounds by high performance liquid chromatography after derivatization to 2,4‐dinitrophenylhydrazones is critically discussed on the basis of a selection of published methods. A method is proposed wh
