  1. 1)

    What is important to help the formation of any MH + ion in PDMS ?

  2. -

    on the sample molecule the intrinsic basicity of the function fixing the proton

  3. -

    on the matrix molecule the acidity of the function giving the proton.

  4. 2)

    What is important to thelp the formation of a protonated peptide ? To break the intermolecular bonds between the different molecules of peptides using a matrix giving small intermolecular interactions sample-matrix and separating the peptide molelcules ones from the others.
