- Abstract:
- Recently, a new multiple-layer matrix-assisted laser desorption/ionization time-of-flight mass spectrometry
(MALDI-TOFMS) sample spotting technique for poly(ethylene glycol), offering improved
analysis possibilities, was described. In this contribution the application of ink-jet printing to automated,
multiple-layer MALDI-TOFMS sample preparation of synthetic polymers is presented,
allowing accurate deposition of matrix, additive and analyte solutions. The new sample preparation
technique was evaluated for poly(ethylene glycol) as well as poly(methyl methacrylate) standards,
and optimized settings for both synthetic polymers have been obtained.
