Gas Chromatography-Mass Spectrometry Paired with Total Vaporization Solid-Phase Microextraction as a Forensic Tool

Overview

Total Vaporization Solid Phase Microextraction (TV-SPME) is a technique that allows for the analysis of a wide range of samples by completely vaporizing a liquid sample while sorbing analytes onto a SPME fiber. This method is particularly advantageous as it can handle dirty samples without the need for filtration.
