AbstractPeak drifts of emission spectral lines recorded on a sequential ICP - AES spectrometer are the main factor that seriously decreases the precision and accuracy of sample determinations. The functional relationships between peak drift Delta lambda, and wavelength lambda, temperature T are found in this paper. The functional relationship curves Delta lambda - lambda, and Delta lambda - T were determined and expressed in the form of polynomial equations. The present study indicates that the curves Delta lambda - lambda for different monochromators are similar, but the curves Delta lambda - T for different monochromators are quite different. Based on the above - mentioned polynomial equations, an intelligent wavelength calibrating device (IWC) is developed for the sequential ICP spectrometer, which can replace a local thermostat of the sequential ICP - AES or the traditional line - profile method. The applications of the sequential ICP - IWC illustrate that the IWC device can significantly improve the precision of peak determination and have widespread prospects.; Peak drifts of emission spectral lines recorded on a sequential ICP - AES spectrometer are the main factor that seriously decreases the precision and accuracy of sample determinations.
