摘要：

A simple method for obtaining laser mass spectra (LMS) of liquids is described using a nitrocellulose membrane or fibrous material as the sample substrate. Laser mass spectra of liquids are presented along with those of solutes in aqueous systems. The use of a liquid matrix with the laser soft ionization method enhances molecular ion formation. Results are presented for charge-transfer derivatization and the influence of solution pH on LMS. © 1990 Springer-Verlag.
