    Abstract: The present disclosure provides a device for generating ionized molecules of interest for analysis in a mass spectrometer. The molecules of interest are desorbed from the device into a desorption solvent. The device includes: a solid substrate having a spray-ionization end and a holding end, the substrate being sized and configured to hold the solvent at the spray-ionization end; and a fluid barrier configured to reduce movement of at least some of the solvent from the spray-ionization end towards the holding end. Methods for analyzing molecules in or from a sample are also provided.
