Abstract: Disclosed herein are methods and systems for ionizing organic compounds by exposing head space vapors to corona discharge. The methods and systems are suitable for high throughput screening of samples, including biofluids. The methods and systems are suitable for rapid evaluation of chemical reactions, permitting discovery of novel organic reaction pathways.

Abstract: Provided herein are apparatuses that can comprise an electrospray emitter comprising a sample capillary extending from a sample inlet to a sample outlet and an element comprising a conduit coaxially disposed around the electrospray emitter thereby forming a chamber extending between the conduit and the sample capillary and terminating in a gas outlet. The element can further comprise, in some examples, a carrier gas inlet fluidly connected to the chamber, and a working gas inlet fluidly connected to the chamber, wherein the chamber is configured to provide a path for fluid flow from the carrier gas inlet and the working gas inlet to the gas outlet. Also disclosed herein are methods of use of the apparatuses. In some examples discussed herein are methods and apparatuses for contained-electrospray, for example for use in mass spectrometry and/or droplet reactions.
