Computer-operated mass spectrometer system

A mass spectrometer-computer system has been devised to utilize the decision-making capabilities of the modern digital computer.The system described assists the researcher user by allowing a computer to query the researcher for operating parameters.The computer translates these into detailed control functions that operate the instrument.The data acquired from the mass spectrometer is made available to the researcher in an on-line system.computer and an integer resolution quadrupole mass spectrometer.A reference gas is valved into the mass spectrometer by computer control to permit automatic calibration.was demonstrated; the means and results are given.
