|
Nearly a dozen incipient technologies have appeared in recent years. Which will survive? Which will find extensive, robust usage as did electrospray ionization? Which are fated to become footnotes in mass spectrometry practice? |

Ionization Revisited
|
December 1, 2006 By:
Michael P. Balogh
|
|
Over the last ten years or so, information gathered by applying atmospheric ionization techniques in mass spectrometry teaches us two things: 1) that liquid is a vestigial remnant of condensed-phase liquid chromatography and 2) that solvent in the gas phase limits ionization to molecules that are more basic than the solvent. |
