Inductively coupled plasma atomic emission spectroscopy (ICP-AES) is a popular analytical technique for routine multielement analysis. An argon plasma, which is sustained by a radio-frequency field, serves as the atomization excitation source for emission spectroscopy. With commercial instrumentation the atomic emission is monitored with either a direct reader (polychromator) or a scanning monochromator. The topic of this paper is the development of software for simultaneous operation of both the polychromator and the monochromator with a single plasma source. The hardware for this system includes an LSI-11/23 as the main computer with satellite FALCON SBC-11/21 single-board computers for hardware control and data acquisition. TSX-Plus, a multi-user operating system, is being employed for software development on the LSI-11/23.
