A modification to a vacuum direct reading optical emission spectrometer is described. The light reflected from the grating is focussed onto the entrance slit of a secondary monochromator to extend the range of wavelengths available. Results for the analysis of sodium in mineral, rock,
and ash samples by a fusion briquette method are given. The application to the analysis of other alkalis and to background correction is discussed.
