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 …
