A novel spectrometer incorporating a multichannel detector for simultaneous multi‐element atomic emission spectrometry (AES) is described. The spectrometer consists of a multi‐bandpass optical filter comprised of a concave and a fiat grating in substractive mode, and a high resolution stage which utilizes an echelle grating and an one inch 1024‐channel photodiode array as the detector. Characterization with respect to the spectral resolution, the spectral response, and the capability of multi‐element detection demonstrated the systems's potential for simultaneous chemical analyses without moving any mechanical parts. To adjust the system for the analyses of different sets of elements, the corresponding mask is simply placed in position.
