    Sammanfattning : In this thesis, new methods that address some current limitations in nanoelectrospray mass spectrometry (nESI-MS) analysis are presented. One of the major objectives is the potential gain in sensitivity that can be obtained when employing the proposed techniques. LÄS MER

  3. 2. On-line Electrochemistry Electrospray Ionisation Mass Spectrometry : Method Development and Applications

    Författare :Camilla Zettersten; Leif Nyholm; Per Sjöberg; Andries P. Bruins; Uppsala universitet; []

    Sammanfattning : This thesis deals with studies of on-line electrochemistry electrospray ionisation mass spectrometry (EC/ESI-MS). It is shown that the use of EC/ESI-MS demands optimal coupling characteristics. Pre-concentration and desalting, due to matrix exchange, were demonstrated for the model substance 1-hexanethiol in an EC/ESI-MS setup. LÄS MER
