Abstract: A hybrid analogue-digital analyzer for the online digitization of electrically recorded mass spectra. The device, which does not incorporate a digital computer, accurately selects peak maxima to provide triggering pulses for timing circuitry, and uses directly controlled buffer storage to reduce the effective rate of data acquisition to that of the average speed of the associated output channel. The analyzer is primarily intended to provide records of complete high resolution mass spectra suitable for off-line computer processing. For real time production of reduced and annotated spectra the analyzer may be used as an active interface directly coupled to a computer.
