    Sammanfattning : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. LÄS MER

  3. 2. Sorption of Cs, Ba, Co, and Eu onto biotite: experiments and modelling
