Electrospray emitter were coated with a low surface energy compound

摘要

To allow the electrospray stable in solution with a large surface tension, such as [challenge] distilled water. Consists of the channel connecting the inlet aperture and the outlet aperture, and their body, it is electrospray emitter portion that can contact with the solution of the tip end of the outlet outer wall is coated with a low surface energy compound, at least, The invention relates to a spray It is a stable electrospray at low flow rate range of nanoliter per minute microliters without using any gas assist. This emitter is the non-conductive, electrospray stable in measurement of the cation-anion which has no risk of discharge prone anion measurement is possible. To prevent loss due to adsorption of analytes by coating with a low surface energy compound the inner wall of the line that connects the analytical instruments such as liquid chromatography and emitter.
