  4. 2. Electrophoretic focusing in microchannels combined with mass spectrometry : Applications on amyloid beta peptides

    Author : Saara Mikkonen; Åsa Emmer; Johan Jacksén; Tapio Kotiaho; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amyloid beta; computer simulation; electrophoresis; electrospray ionization; isoelectric focusing; isotachophoresis; MALDI; mass spectrometry; microchannel; microchip; nano-electrospray ionization; preconcentration; separation; Kemi; Chemistry;

    Abstract : Analysis of low-abundance components in small samples remains a challenge within bioanalytical chemistry, and new techniques for sample pretreatments followed by sensitive and informative detection are required. In this thesis, procedures for preconcentration and separation of proteins and peptides in open microchannels fabricated on silicon microchips are presented. READ MORE

  5. 3. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations

    Author : Saara Mikkonen; Åsa Emmer; Leopold Ilag; Jenny Ottosson Takanen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Preconcentration; open microchannel; microchip; MALDI; electrospray ionization; nanoelectrospray; mass spectrometry; computer simulation;

    Abstract : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).
