There are two integrators that you can use with the MSD Chemstation. One is the “RTE” integrator, and the other is the “Chemstation” integrator. The RTE is named that way because it is similar to the integrator from another data system that Hewlett Packard or Agilent used to sell called the RTE Data System. It was written to integrate mass chromatograms. It does NOT have timed events. Users who need timed events may prefer to use the Chemstation integrator. Timed events allow you to control integration on a time basis, such as turning the integrator ON at 2.0 minutes and then OFF at 3.0 minutes. The RTE integrator allows you to integrate the chromatograms using unique tools or filters such as “maximum number of peaks”, and “area percent”. The RTE is useful if you want to integrate the top “X” peaks based on area, such as the top 5 peaks by size. The Chemstation integrator is useful when you need timed events, such as when you have a varying baseline from something like column bleed in
