Abstract
The design, construction, and performance of a multichannel flame spectrometer has been reported (1). In the present paper, the use of the instrument for the simultaneous determination of magnesium, calcium, copper, manganese, and chromium is described. The over-all precision of the measurements of these elements is assessed. The effect of cations and anions on the measurements is determined, and the accuracy of analysis ascertained by measurement of certified standards of the National Bureau of Standards. The work has demonstrated the feasibility of simultaneously determining all of these alkaline earth and transition metals with this multichannel flame spectrometer (1). Experiments designed to demonstrate the suitability of the system for the analysis of metals in biological materials are also performed.
