Practical problems concerning the application of our previously reported spectrochemical method for routine industrial analysis were studied. The differences and variation of the components between the sponge titanium sample solution and the spectrochemical standard solution of titanium tetrachloride and hydrochloric acid, and the evaporation of impurity elements while titanium sponge was dissolved were negligible. The change in the percentage of Si in the spectrochemical standard solution while standing was found by observation of relative intensity for 6 months, and correction procedures are proposed. Various physical properties of carbon electrodes for spectrochemical analysis were evaluated. The effect of the quality of carbon electrodes on the analytical accuracy and precision are described. Finally, some methods for increasing the analytical range are described.
