ABSTRACT:
There is provided a method for sample introduction into a mass spectrometer for performing sample analysis, including desorbing a sample by a laser beam and forming gaseous sample compounds, sweeping desorbed sample compounds with a carrier gas into a transfer line, transferring the sample compounds in the transfer line into a supersonic nozzle, expanding the sample compounds mixed with the carrier gas from the supersonic nozzle to form a supersonic free jet inside a vacuum chamber of a mass spectrometer, and ionizing and mass analyzing the sample compounds for the purpose of identification and/or quantification of the sample. An apparatus for carrying out the method is also provided.
