Thanks to the dedicated efforts of so many in my Administration, the bipartisan push for reform from federal, state, and local officials, and the work of so many committed citizens outside government, America has made important strides. We have reduced overlong sentences for offenders and removed barriers for those with criminal records. We have made progress in helping people, especially young people, avoid getting entangled in the justice system in the first place. This Commentary talks about those achievements — and …

Rapid Analysis Of Forensic-Related Samples Using Two Ambient Ionization Techniques Coupled To High-Resolution Mass Spectrometers, Eshwar Jagerdeo, Amanda Wriston

United States Department of Justice: Publications and Materials

RATIONALE: This paper highlights the versatility of interfacing two ambient ionization techniques, Laser Diode Thermal Desorption (LDTD) and Atmospheric Solids Analysis Probe (ASAP), to high-resolution mass spectrometers and demonstrate the method’s capability to rapidly generate high-quality data from multiple sample types with minimal, if any, sample preparation.

METHODS: For ASAP-MS analysis of solid and liquid samples, the material was transferred to a capillary surface before being introduced into the mass spectrometer. For LDTD-MS analysis, samples were solvent extracted, spotted in a 96-well plate, and the solvent was evaporated before being introduced into the mass spectrometer. All analyses were performed using …
