Solid phase microextraction (SPME) was used to sample the headspace, and determine the volatile organic compounds (VOCs) of pig organs after a year of decomposition. Gas chromatography mass spectrometry (GC/MS) was used to analyze samples to identify the specific VOCs. Several SPME fibers, including PDMS/DVB, Carboxen/PDMS, and DVB/Carboxen/PDMS, were used to sample each of thirteen pig organs. Some of these organs included the brain, heart, muscle, kidney, fat, and blood. This paper will report the VOCs found in the organs by each SPME fiber.
