Title: Ion association by time-of-flight mass spectrometry
Abstract: Time-of-flight mass spectra are normally obtained by averaging repetitive mass scans of ions accelerated from a pulsed source. In the present work, individual mass scans from each pulse were tested for probable associations between ions of different m/z, i.e., was the presence of one ion contingent upon the presence of the other in the same scan? The tendency for ions to be associated was evaluated statistically by testing data obtained from solid specimens of cesium iodide and the superconductor, YBa2Cu3O7. The individual ion pulses were produced by laser desorption using a 300 ps uv nitrogen laser. The laser energy density was maintained near the threshold for ion production so that only a few ions were generated per laser pulse.
