IONIZATION METHOD AND DEVICE

摘要

Provided are an ionization method and device. The ionization method comprises an ion source, a sample and a mass spectrum sample injection channel, and is characterized in that the ion source is flame. The ionization method, by using flame as the ion source, is not only easily realized and simple to operate and greatly reduces the analysis cost, but also has a strong compatibility, can satisfy ionization dissociation temperature requirements of compounds with different molecular weights and has a good ionization efficiency for any of gaseous, liquid and solid samples. Not only is the sensitivity high, but also a direct analysis can be carried out on actual samples. Moreover, the ionization of materials such as polar, highly polar, non-polar, metal organic compounds can be well achieved. The method has a wide range of application, can be used together with portable mass spectrometry to achieve more convenient natural state in-situ analysis, and has a remarkable practical value.
