Abstract
Sampling probes and interfaces for mass spectrometry systems and methods are described to analyze a composition of a substance. The system includes a liquid reservoir containing solvent; a gas reservoir containing nebulizer gas; a conduit that is in fluid communication with the liquid reservoir, the conduit comprising a first and second portion and a junction portion, the first and second portion being joined at the junction portion, and defining an angle therebetween at the junction and the junction portion contains an aperture that is open to the atmosphere. A nebulizer conduit that is co-axial and partially surrounds the second portion and completely surrounds an end of the second portion can also be present, the nebulizer conduit being fluidly connected to the gas reservoir and that allows a gas to flow from the gas reservoir over an external surface of the second portion and the end of the second portion.
