An instrument for multielement flame emission analysis is described which consists of a 0.5m Ebent monochromator, a silicon diode vidicon tube, and an optical multichannel analyzer. Optical and electronic considerations of the system are discussed. Using this system, a spectral window'' of 20 nm is monitored simultaneously and atomic lines 1.4 A apart are resolvable. Detection limits, obtained under compromise flame conditions, are presented for Mo, Fe, Ca, Al, Ti, W, Mn, and K using spectral lines present in a single window. The multielement analysis of a geological standard rock sample for Fe, Ca, Al, and Ti is described, and the results are compared with the accepted values. Other potential windows for multielement analysis are presented. (auth)
