Rapid and Simultaneous Determination of Volatile Fatty Acids and Indoles in Pig Slurry and Dog Excrement by Solid-Phase Micro-Extraction Method with Gas Chromatography
Rapid and Simultaneous Determination of Volatile Fatty Acids and Indoles in Pig Slurry and Dog Excrement by Solid-Phase Micro-Extraction Method with Gas ChromatographySPME;Pig slurry;Dog excrement;Odor;Volatile fatty acids;Indoles;A rapid and simple method for the quantitative determination of volatile fatty acids (VFAs; propionic acid, n-butyric acid, i-valeric acid and n-valeric acid) and indoles (phenol, p-cresol, 4-ethyl phenol, indole and skatole) in pig slurry and dog excrement using solid-phase micro-extraction (SPME) coupled to gas chromatography was evaluated.
