Description

technical field [0001] The disclosure belongs to the technical field of mass spectrometry detection and analysis, and relates to a thermal desorption and dissociation device in a mass spectrometer, in particular to a sampler, a rapid heating sampling system and a rapid detection method. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Mass spectrometry is an analytical method for measuring the mass-to-charge ratio (mass-to-charge ratio) of ions. The action of the accelerating electric field forms an ion beam that enters the mass analyzer. In the mass analyzer, the electric and magnetic fields are used to make the opposite velocity dispersion occur, and they are respectively focused to obtain a mass spectrum, thereby determining its mass. [0004] A mass spectrometer is based on an ionization device, a mass analyzer, and an ion detector. The det...
