Equipment type: Matrix-Assisted Laser-Desorption/Ionization Time-of-Flight Mass Spectrometer (MALDI/TOF-TOF MS)
Manufacturer / Brand: Bruker/ UltrafleXtreme
usage: Determination of absolute molecular weights of polymers up to 105 Da, their chemical composition, type of functional groups, microstructure (sequence), identification of impurities and other by-products (cyclic structures, etc.). . If MS instrument is coupled to a liquid chromatography (SEC, HPLC) the distrubution properties of polymers can also be determined, i.e., distribution in molecular weight, functionality or composition.
of application for polymer analysis / information that can be obtained by this method for polymers: determination of molecular weight, functionality, structure
range: up to 105 Da
Sample limitations: samples difficult to ionize
