摘要: This time-of-flight mass spectrometer utilizes the 252Cf fission fragment-induced ionization of organic solids and electrostatic desorption. It is designed for high sensitivity needed in quantitative analysis pharmaceuticals can be combined with a high-performance liquid chromatograph. The solute emerges into rough vacuum stage sampling up to twelve fractions vacuum-drying process. Samples low vapor pressure are introduced periodically ion source by means an interfacing disk analysed successively. detection employing conversion electrons microchannel plates investigated. performance discussed terms resolution, efficiency reproducibility.
