The paper describes the hardware, software and algorithms for
the upgraded automated data acquisition system of the MU1201 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.
