The application of an IR laser working at a wavelength of 3.27 mm, for matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry and matrix-less laser desorption/ionization of different polymers, has been demonstrated. The ionization/desorption of polyethyleneglycols (PEG) and po

Sample preparation
All polymer samples were from commercial sources and used without further purification. PEG-2OOO dimethyl ether, PEG-4000, PEG-6000, PEG-10 OOO and PEG-35 OOO were purchased from Fluka (Buchs, Switzerland). The Polystyrene (PS) standards PS12500, PS/3700, PS/12500, PS35 OOO and polybutadiene (phenyl terminated) PB-1800 were all obtained from Aldrich (Buchs, Switzerland). The phenyl terminated polybutadiene

Protonated molecules of analytes in matrix-assisted laser desorption/ionization (MALDI) are frequently the most intense ions observed, especially when the concentration of alkali metal cations is low. Examination of the laser desorption mass spectra of MALDI matrices usually shows the presence of bo
Previous modelling of the matrix-assisted laser desorptiodionization (MALDI) process has had to rely on matrix solution optical absorptivities whereas the value for the solid phase is more appropriate. Absorption bands are usually broader for solids than for solutions due to the higher concentration
Lignin is one of the components, with cellulose and hemicellulose, of cell walls in all terrestrial plants. Lignin is an amorphous, three-dimensional, polyphenolic molecule charged with the function of giving strength and impermeability to the plant structure. The determination of its molecular weig
Cation attachment during matrix-assisted laser desorption/ionization (MALDI) of various synthetic polymers was investigated. The ions were created in a field-free source and extracted by a pulsed electric field applied at a known and variable time delay after the laser pulse. This is shown to increa
