摘要：

A method is described for obtaining quantitative intensity data from solution-state spectra by a combination of coaxial tubes and sample replacement to take account of spectrometer electronic effects. The protocol was applied to two sodium silicate solutions of high silica content, and it is shown that there is no 'invisible' silica at the concentrations studied.
