A low temperature plasma probe, a mass spectrometry system, and a method for using a low temperature plasma probe are described. In an embodiment, a low temperature plasma probe includes an intake capillary that provides an ion flow from a sample surface to a mass spectrometer; at least one low temperature plasma tube that provides low temperature plasma gas; at least one heated gas tube that provides heated gas to the sample surface, where the heated gas enhances desorption and ionization of a sample on the sample surface.
