Report Date

March 2020

Description

This report summarizes the development and implementation of a novel sampling device (capillary microextraction of volatiles [CMV]) invented in the Almirall research group at Florida International University for ILR extraction as an alternative to current techniques. The versatility of the CMV device has the potential for field sampling applications when coupled with portable analytical systems, and it has been successful in the following studies: sampling volatile compounds generated by explosives, detecting marijuana plants, detecting volatile organic compounds (VOCs) released from amphetamines, analyzing breath samples, sampling organic gunshot residue (OGSR) VOCs, and sampling BTEX (benzene, toluene, ethylbenzene, and the three xylene isomers) compounds in environmental studies. This report is intended for forensic practitioners who want to better understand newly developed technologies and their use and application to forensic casework.
