Forensic Discrimination of Oils by Matrix Assisted Laser Desorption Ionization Time Of Flight Mass Spectrometry (MALDI-TOF-MS)
STAGE DOI: 10.3408 / jafst.754 ) Triacylglycerols ( TAG ) are composed of three esteriˆed fatty acids bound to a glycerol backbone and are the main components of several types of edible or cook-ing oils. An oil such as salad oil is occasionally used for a crime and is left in the crime scene as physical evidence. In criminal investigation, one of important evi-dence is to identify the kind of oil. Therefore, matrix assisted laser desorption ionization time of ‰ight mass spectrometry ( MALDI TOF MS ) was used for forensic discrimination of oils. In this study, pencil lead as a matrix was used.
