  1. 1. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    University dissertation from Stockholm : KTH

    Author : Patrik Ek; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers.All present-day nanoelectrospray emitters have fixed dimensions. READ MORE
