Abstract
A simple multiwavelength emission instrument utilizing a commercial grating monochromator, a fiber optic sensor to collect radiation from an acetylene‐air flame, and a CCD detector, has been evaluated for pedagogical value in the undergraduate curriculum. Simultaneous determination of Na, Li, K, Rb at ppb level, and Ca, Sr, Ba at ppm level was achieved. The instrument is affordable, yet suitable for solving real analytical problems. High quality visualization makes the spectrometer a useful educational tool.
