Desorption of metasilicate and related polysilicate ions from sodium silicate solution by liquid-target secondary ion mass spectrometry

Secondary Ion Mass Spectrometry of Zeolite Materials: Observation of Abundant Aluminosilicate Oligomers Using an Ion Trap

“…The low abundance of the larger mineral anions is a significant limitation, because they necessarily contain the richest chemical information that describes the surface and are the most interesting for conducting ion−molecule reactivity studies. Oligomeric silicates Si x O y H z - were observed by Bursey and Marbury, who were able to sputter species to x = 4 from a basic sodium silicate solution . Similar species were generated by three different groups using laser desorption. − More recently, Lafargue and co-workers were able to observe abundant silicate oxyanions using laser desorption Fourier transform mass spectrometry. , Silicate oligomers up to x = 11 were generated, and they also noted relatively fast addition of gaseous H 2 O to these species.…”
