Liquid secondary ion mass spectrometric investigation of ion-pair precipitates of some ethoxylates with barium tetraphenylborate
Liquid secondary ion mass spectrometry seems to be useful technique for the qualitative characterization of ion-pair precipitates of ethoxylates with barium tetraphenylborate. In the positive mode, barium complexes of ethoxylates were examined. In the negative mode, the ion signal of tetraphenylborate had 100% intensity relative to the matrix peaks. The low-resolution mass spectra were found to be suitable for checking the purity of ion-pair precipitates of ethoxylates with barium tetraphenylborate. On the basis of B/E mass spectra, the fragmentation routes of [M - H + Ba](+) ions are proposed. Copyright 2000 John Wiley & Sons, Ltd.
