Abstract

A GC/MS study was performed in order to determine 1,4‐benzoquinone, 1,4‐cyclohexanedione, and hydroquinone derivatives on by one and in the presence of each other in different concentrations. Exhaustive investigations, related to the quantitation both of their underivatized compounds and those of their oxime/methoxime and silyl derivatives. Results proved that subsequently to the oximation/methoximation of the carbonyl groups – for the sake of a well shaped and accurately evaluable hydroquinone peak – also silylation is unavoidably necessary. Reproducibility data in the microgram/nanogram level, based on quantitation of their total ion currents and/or those of their selective fragments, were given in details.
