Description The generation and identification of novel homo- and hetero-polyacid clusters from concentrated sulfuric acid, selenic acid or their mixtures, was achieved using a standard LDI-TOF MS. A quantity of novel species was observed in the negative detection mode, e.g. HSeO4-.X (X = SeO3, H2SeO4, 2SeO3, H2SO4.SeO3).
