Thermal desorption with uv irradiation with subsequent ionization systems and methods

Abstract

A system and a method for thermal desorption using UV irradiation and subsequent ionization for sensing, monitoring, and identification of analytes are provided. In one or more embodiments, the system may include an ultraviolet light-emitting-diode (UV LED) source configured to emit radiation for desorbing analytes from a sample, an ionization source configured to ionize the desorbed analytes to produce ionized molecules at an atmospheric pressure, and a charged particle analyzer configured to analyze the ionized molecules to determine or identify a chemical composition or a chemical structure of the desorbed analytes. The method may include irradiating a sample comprising analytes via the UV LED source, ionizing the desorbed analytes to produce ionized molecules at an atmospheric pressure, and determining a chemical composition or a chemical structure of the desorbed analytes.
