pn02.jpg (9108 bytes)The Agilent 5973 Network Mass Selective Detector (MSD) and MSD Productivity ChemStation software, when combined with one of this company’s gas chromatographs, form a versatile gas chromatograph/mass spectrometer (GC/MS) system for chemical analysis.
     The push buttons and display of a recently added local control panel allow the operator to check instrument status, change setpoints, start a tune, method, or sequence, and run system diagnostics. These functions can be performed without touching the data system. For many labs, this is all the control that operators require, if method development and data analysis are done elsewhere via LAN-based instrument communication.
     A single data system can now control two MSDs, up to four GCs or a any combination up to a total of four detectors. Multi-instrument control is helpful in high-volume labs with routine, automated data analysis or off-line data analysis and where space and cost are considerations.
     The 5973N MSD works with either of this company’s gas chromatographs. The 6890 Plus GC is suitable for applications that require versatility. With an optional autosampler and 100-sample tray, it is capable of running samples around the clock. The small, single-channel 6850 Series GC is suitable for simple, low-volume, EI analyses.
     The enhanced MSD Productivity ChemStation software features sequences that can be set up by importing sample work lists in comma separated value format; closed-loop retention time locking capabilities that automatically compensate for retention time changes that take place during long sequences; sample-centric software, which means the operator does not have to know which method is required for a particular sample. They enter only the sample name and the early maintenance feedback software notifies them when their system is due for maintenance. Agilent Technologies
