Abstract
A device is described for generating ionized molecules for analysis in a mass spectrometer. The device includes: a solid substrate having one or more edges and a coated area that is coated with an extraction phase comprising an extraction polymer. The solid substrate may have at least two edges that meet at an angle from about 8° to about 180°. Mass spectrometry systems that include such a device are also described. Methods of analyzing a molecule previously extracted from a sample onto the device are also described.
