The invention provides a mass spectrometry interface for collecting ions and directing a drying gas. The mass spectrometer interface may be used independently or in combination with an ion source and a mass spectrometry system. The mass spectrometer interface, includes a body portion having a first open end; and a tip portion in contact with the body portion having a second open end and a wall with an aperture for receiving ion, the wall having a cross-sectional area that tapers from the first open end of the body portion toward the second open end of the tip portion, wherein the mass spectrometer interface may direct a gas from the first open end of the body portion toward the second open end of the tip portion and the aperture in the wall of the tip portion may receive ions for drying by the gas.The invention also provides methods for ion collection and drying. The method for collecting and drying molecules, includes directing ions through an aperture of a closed mass spectrometry interface; and drying the molecules using a drying gas.
