Quantitative studies of the complexation of the macrocylic ligands, 18 crown 6 (18C6,1) and cyclogentiotetraose peracetate (CGD4Ac,2), with alkali cations, have been investigated by fast atom bombardment mass spectrometry (f.a.b.m.s.). Complexation curves of 18C6 with Na+, K+, Rb+ and Cs+ in glycerol, and of CGD4Ac with Cs+ in PEG 200, were obtained by plotting the complex peak intensity against the alkali cation concentration. From these curves we describe a method to calculate the stability… Expand
