Abstract This study describes a rapid and simple method to determine short-chain fatty acid (SCFA) concentrations and their isotopic enrichments (M 0+ 1 and M 0+ 2) in human plasma. Sample preparation involves SCFA extraction and derivatization with 1-(tert- butyldimethylsilyl) imidazole. Gas chromatography/mass spectrometry was performed using chemical ionization with ammonia as the reagent gas. Outstanding resolution, excellent ...
