Potential of gas chromatography in the determination of low-volatile dicarboxylic acids

Determination of some short chain carboxylic acids in food by headspace gas chromatography

“…There are some works on the direct GC determination of short chain carboxylic acids without their derivatization [5,20]. Zenkevich et al [20] suggest that derivatization is desirable or necessary for simple dicarboxylic acids but could be omitted for monocarboxylic acids.…”

“…There are some works on the direct GC determination of short chain carboxylic acids without their derivatization [5,20]. Zenkevich et al [20] suggest that derivatization is desirable or necessary for simple dicarboxylic acids but could be omitted for monocarboxylic acids. Thus, to verify the possibility of gas chromatographic determination of the analytes of interest (acetic acid, propionic acid, oxalic acid and succinic acid) without their derivatization, the solutions of the acids in acetone were directly injected into the GC system.…”
