Electrospray devices for mass spectrometry

摘要

An electrospray device (108) for a mass spectrometry system (100) is described. The electrospray device (108) comprises a body portion (116) and a tip portion (118) extending from the body portion (116). The tip portion (118) comprises a polymeric material. The electrospray device (108) also comprises a hydrophobic coating (160) substantially selectively covering the tip portion (118).
