| Abstract: | Field desorption of negative ions can be achieved below the threshold of field electron emission. To this end a mixture of the sample with polyethylene oxide and water was applied to smooth wire cathodes. The mass spectra of some inorganic and organic compounds are reported. Anionization by [CI]? ion attachment is demonstrated with the examples of 20-hydroxycholesterol and sucrose. |
