A Novel Derivatization Reagent in the Determination of the Number of OH End Groups in Poly(ethylene glycol) by Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry
{{output}}
The potential of a novel derivatization reagent, trifluoroacetic anhydride (TFAA), in determining the number of OH groups in poly(ethylene glycol) (PEG) was investigated by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). The MALDI mas... ...
