An automated system for providing at least one sample for electrospray ionization in a mass spectrometer system

Abstract

An automated system (112) for providing at least one sample (136) for electrospray ionization in a mass spectrometer system (110) is disclosed. The automated system (112) comprises: •at least one electrospray emitter (122) comprising at least one emitter end (120) having at least one emitter tip (124) and at least one fluid-entrance end (126); •at least one autosampler (132), wherein the autosampler (132) comprises at least one autosampler outlet (134), wherein the autosampler (132) is configured for providing at least one sample (136) having at least one analyte; •at least one pipe (138) having at least one pipe fluid-outlet end (142) and at least one pipe fluid-inlet end (144), wherein the pipe fluid-inlet end (144) is fluidically connected to the autosampler outlet (134); •at least one liquid junction (146), wherein the liquid junction (146) comprises at least one connecting element (148) being made of at least one electrically conductive material, wherein the connecting element (148) receives the fluid-entrance end (126) of the electrospray emitter (122) and the pipe fluid-outlet end (142) of the pipe (138) such that a fluid connection between the electrospray emitter (122) and the pipe (138) is established, wherein the connecting element (148) is electrically connectable to at least one voltage source; wherein the emitter tip (124) comprises an opening having a diameter of 1 μm to 10 μm.
