Upgrading the data acquisition system for МИ1201 continuous scanning mass spectrometers

The paper describes the hardware, software and algorithms for the upgraded automated data acquisition system of the МИ1201 mass spectrometer. The system performs mass spectrometric data collection, processing and presentation, which is used in the production and control cycle at industrial plants. The upgraded system consists of a precision electrometric amplifier, 24-bit analog-to-digital converter with a low-pass filter, magnetic field controller with galvanic decoupling. The algorithms and programs used are based on typical mass spectrometric procedures and the authors' original methods for mass spectrometric peak detection and measurement error correction for insufficient resolution and great differences in height of adjacent peaks.
