OA detection with qualitative gas chromatography-mass spectrometry assays is problematic for 2 reasons: First, OA is a charged nitrogen species of high polarity and does not extract into organic solvents with high efficiency; second, OA often coelutes with the tricarboxylic acid cycle intermediate cis-aconitic acid on many gas chromatography columns.
