摘要：

A membrane consisting of polymeric film densely perforated with channels is used as the interface between a solution at atmospheric pressure and the vacuum chamber of a mass spectrometer. It is shown that an electric field can stimulate ion emission from the liquid sample directly into the vacuum. Emitted ions were investigated with a time-of-flight mass spectrometer.
