The presence of different equilibrated chemical species in aqueous solutions of polyoxometalates represents a challenge for their identification, requiring the use of both separation and detection techniques. The use of reversed-phase ion-pair high-performance liquid chromatography (HPLC) in gradient elution mode resulted in optimal separation conditions. The detection was accomplished by parallel hyphenation of the inductively coupled plasma atomic emission spectrometry (ICP-AES) and electrospray ionization mass spectrometry (ESI-MS), which combined the advantages of element and molecule specific detectors. This hyphenation resulted in an unambiguous identification of the products of the synthesis of mixed-addendum Keggin-type phosphovanadotungstates of [PVxW12-xO40](3+x)- (x = 1– 3) general formula without the isolation of the individual species.
