摘要: MALDI-TOF MS is used to analyze the chain lengths and endgroups of fatty alcohol ethoxylates based on fragmentation behavior in collision-induced dissociation. MALDI-CID-TOF2 results complex patterns that mirror ethylene oxide oligomer alocohol endgroups. Characteristic fragment are obtained facilitate interpretation ethoxylates. Linear branched can be differentiated specific fragments identified characteristic for cleavage between polymer endgroup. These “marker” determine length number carbons per
