Overview

The work in this report is an extension of the capillary microextraction of volatiles (CMV) application (M. Torres et al., 2020) by Florida International University, reported by the Forensic Technology Center of Excellence (FTCoE) in April 2020. This technical note details the optimization of a field-sampling protocol originally used with solid phase microextraction (SPME), now adapted for use with the CMV (M. N. Torres & Almirall, 2022). Following the optimization, Florida International University researchers extracted ILRs from simulated fire debris and analyzed the extracted compounds using a portable GC-MS unit. Finally, qualitative sampling researchers conducted at a controlled structural fire for a preliminary field assessment of the sampling protocol and portable unit.
