Abstract Details

2022, Master of Science (MS), Bowling Green State University, Forensic Science.
908 Devices has created a handheld High-Pressure Mass Spectrometer™ (HP-MS), called the MX908®, for field analysis of unknown substances. According to the manufacturer, the MX908® has a theoretical limit of detection in the low to mid parts per billion (ppb) range, but because the device provides qualitative rather than quantitative data, the actual limits of detection are unknown. The purpose of this experiment was to determine a limit of detection and sensitivity of the MX908® for methamphetamine, fentanyl, heroin, and cocaine by comparing known standards for each drug processed on the MX908® and a Shimadzu 8050 triple quadrupole Liquid Chromatograph Mass Spectrometer (LC-MS). Samples were spotted directly on the MX908® swabs and spotted on a table and swabbed off. This was to compare a controlled setting to a simulation of a practical use of the swabs and instrument. Cocaine and methamphetamine were the only two drugs reliably detected by the instrument. More testing is necessary to validate the MX908® for future use
