Nano-liquid chromatography-direct electron ionization mass spectrometry: improving performance by a new ion source adapter

Autor: Michael Karas, Christian Wolf, Cornelia Flender, Peter Leonhard

Publikováno v: Journal of Mass Spectrometry. 46:1004-1010

A novel interface adapter has been designed to provide a new way of directly coupling a nano-liquid chromatograph to an electron ionization mass spectrometer. It connects the transfer capillary coming from the liquid chromatograph to the ionization c
