Liquid chromatography (LC)/electro-chemistry/mass spectrometry (MS) with atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) has been used for the determination of several alcohols and alkylphenols in gasoline and diesel fuels. After rapid sample preparation and a derivatization step with ferrocenecarboxylic acid chloride, the LC separation resulted in complex chromatograms...
Rapid liquid chromatographic separations of ferrocenecarboxylic esters of various alcohols and phenols have been achieved on reversed-phase columns of 20 mm length. After separation, the ferrocene derivatives are oxidized electrochemically under formation of the charged ferrocinium species, which are easily detected by mass spectrometry using an atmospheric pressure chemical ionization source operated...
