“…Recently, capillary zone electrophoresis (CZE) with UV and fluorescence detectors has been used extensively [10]. Cugat et al have reviewed a large number of electrophoretic methods for the determination of benzene and naphthalene sulfonates in aquatic environment [11]. Numerous LC methods with different detection systems, such as UV, fluorescence and particle beam electron impact mass spectrometry, have been reported in the literature [12 -17].…”

A simple and rapid gradient elution high-performance liquid chromatographic method using photodiode array and electrospray ionization mass spectrometric detectors was developed for separation and determination of the process-related substances and photodegradation products of stilbenesulfonic acids, viz. 4,4'-dinitrostilbene-2,2'-disulfonic acid (DNSDA), 4-amino-4'-nitrostilbene-2,2'-disulfonic acid (ANSDA), and 4,4'-diaminostilbene-2,2'-disulfonic acid (DASDA) in industrial waste waters. Gradient elution was carried out using ammonium acetate and acetonitrile as mobile phase and an Inertsil-ODS 3V column for separation. The negative-ion electrospray ionization mass spectra containing [M-H]- ions of sulfonic acids allowed molecular mass determination of unknowns and the structures were proposed on the basis of the fragment ions in the MS/MS spectra.
