Abstract: A spectrometer readout system with storage capacitors for temporarily storing output signals generated by a series of photomultiplier tubes that are positioned to monitor selected spectral lines. A voltage-time converter sequentially discharges the capacitors to a preset level and converts the stored voltages into signals that are related logarithmically to a known signal and an unknown signal. The output of the voltage-time converter defines the log discharge time period which is measured and stored by a computer.

Abstract: A spectrometric system for multielement analysis and a cassette for use in such system, the cassette having a plurality of aligned and nonaligned channels therethrough, each of which has an inlet and an outlet, the inlets in the focal plane of the spectrometer, and each outlet adjacent a photomultiplier tube, and optical transmission means within the cassette to transmit spectral emission radiation received by the nonaligned inlets through channels to the photomultiplier tubes adjacent the nonaligned outlets for such channels.
