| 摘要 |
A mass spectrometry ionization method in which electrospray droplets or soli d sample matrices are exposed to an ion beam thereby increasing the unbalanced charge of the analyte is provided. In another embodiment, a mass spectrometr y ionization method in which ionization of the sample is achieved by directing an ion beam at a liquid or solid sample matrix containing analyte thereby ionizing and adding unbalanced charge to the analyte is provided. |
