A Study on an Europium(III) Cryptate by Electrospray Mass Spectrometry

Abstract Electrospray mass spectrometry (ESMS) of an europium(III) cryptate derived from tris(2-aminoethyl) amine (tren) and 2,6-diformyl-4-chloro-phenol (dcp) is described. The effect of mobile phase, needle voltage and temperature of heated capillary on the ESI process are studied to get the best experimental parameters. The ES-induced fragmentation mechanism is discussed.
