Section 1: Getting started Welcome to MON 20/20—a menu-driven, Windows-based software program designed to remotely operate and monitor the Daniel® Danalyzer™ XA series and the Rosemount® Analytical XA series of gas chromatographs. MON 20/20 operates on an IBM-compatible personal computer (PC) running the Windows XP operating system or later.
User Manual MON20/20 Software for Gas Chromatographs 3-9000-745 OCTOBER 2010 MON 20/20 can generate the following reports: • 24-Hour Averages • Analysis (GPA) • Analysis (ISO) • Calibration • Final Calibration • Validation • Final Validation • Hourly Averages • Monthly Averages • GC Configuration • Raw Data • Variable Averages • Weekly Averages • Dew Temperature Calculation (optional) MON 20/20 can access and display the following GC-generated logs: • Alarm Log • Event Log • Parameter List • Maintenance
MON20/20 Software for Gas Chromatographs OCTOBER 2010 1.1 User Manual 3-9000-745 What’s new in MON 20/20 Users familiar with MON2000 or MON2000 Plus will find a few changes when using MON 20/20: • Login security is at the gas chromatograph level instead of at the software level. This means that you no longer have to log in after starting MON 20/20—but you do have to log in to the gas chromatograph to which you are trying to connect.
User Manual MON20/20 Software for Gas Chromatographs 3-9000-745 OCTOBER 2010 • Enhanced Chromatogram Viewer. The following enhancements have been made to the Chromatogram Viwer: - - - - - Users can view an unlimited number of chromatograms, in any configuration. For example, a user can view an archived chromatogram and a live chromatogram. For more information, see “Viewing chromatograms” on page 2-1. The “Keep Last CGM” option.
MON20/20 Software for Gas Chromatographs OCTOBER 2010 User Manual 3-9000-745 • Baseline offsetting. In some situations that involve TCD detectors the baseline may be displayed either too high on the graph, in which case the tops of the peaks are cut off, or too low on the graph, so that the bases of the peaks are cut off. If this occurs it is possible to offset the baseline either up or down so that the entire peak can be displayed on the graph.

Appendix B, Data computations A B.1 Data acquisition Every second, exactly 50 equally-spaced data samples are taken (i.e., one data sample every 20 milliseconds) for analysis by the controller assembly. As a part of the data acquisition process, groups of incoming data samples are averaged together before the result is stored for processing. Nonoverlapping groups of N samples are averaged and stored, and thus reduce the effective incoming data rate to 40/N samples per second.
User Manual 3-9000-745 B.2 MON20/20 Software for Gas Chromatographs OCTOBER 2010 Peak detection For normal area or peak height concentration evaluation, the determination of a peak's start point and end point is automatic. The manual determination of start and end points is used only for area calculations in the Forced Integration mode. Automatic determination of peak onset or start is initiated whenever Integrate Inhibit is turned off.
MON20/20 Software for Gas Chromatographs User Manual OCTOBER 2010 3-9000-745 The zero reference line will, in general, be non-horizontal, and thus compensates for any linear drift in the system from the time the peak sequence starts until it ends. In a single peak situation, peak area is the area of the component peak between the curve and the zero reference line. The peak height is the distance from the zero reference line to the maximum point on the component curve.
