Thermal desorption free device, mass spectrum system, and mass spectrum analysis method

Thermal desorption free device, mass spectrum system, and mass spectrum analysis method

A thermal desorption free device is used for disportion of a to-be-detected object and moving the object to an inlet of a mass spectrum apparatus for mass spectrum analysis. The thermal desorption free device comprises a charge generating unit, a heating unit and a sampling unit. To-be-analyzed matt...

description A thermal desorption free device is used for disportion of a to-be-detected object and moving the object to an inlet of a mass spectrum apparatus for mass spectrum analysis. The thermal desorption free device comprises a charge generating unit, a heating unit and a sampling unit. To-be-analyzed matters of solid and liquid are directly scrapped or adhered by a probe of the sampling unit and then are insantly gasified when the probe is passing by a channel of the heating unit, and free and mass spectrum analysis is conducted through cooperation of the charge generating unit, thereby greatly shortening the time for analysis of the to-be-analyzed matters. The invention also provides a mass spectrum system including the thermal desorption free device, and a mass spectrum analysis method using the mass spectrum system.
