The Agilent HP 5971 Mass Spectrometer (MS) is a standalone detector designed for use with the HP 5890A Gas Chromatograph (GC). This system has a mass range of 10-650am.
Mass Selective Detector (MSD) electronics provide real-time control according to setpoints and instructions from the data system which sends operating parameters to the MSD. Status information and data originates from the MSD before transferring to the system.
The data system software included in this gas chromatograph is useful for editing and file management. It is equipped with programs that can acquire and process data as well as calibrate the MSD and other utilities. Tuning programs can calibrate mass assignments, control scanning of mass analyzers and adjust voltages in the ion source. Monitoring of total ion current and saved concentrations of particular ions can be performed with data gathering systems. The use of data acquisition programs is advisable when automatically storing the mass spectra of GC peaks as they elute.
