The Problem Of Spectral Analysis Of Glasses With The Use Of Sliding Discharges (In Russian)

The low volt spark discharge over the surface of the specimen allowed trace analysis to be carried out without preparation of powder and further excitation by some conventional methods. The Na2O. 3SiO2 glass contained small amounts of P, and the spectrometer provided four spectra on one film. Background near the analytical lines was used as the internal standard, the calibration curves indicate a high concentration sensitivity. Both vacuum is applied in case of difficult-to-excite elements in the glass.
