Temperature, Pressure, Flow, Rate, Animation, Automatic Optimization Algorithm, flexible. GC Simulation, retention simulation
Our development focus:
now shipping version 6.0!
Latest version includes a rich set of unique and powerful features- making it easier to develop more efficient methods than ever before.
GC-SOS:  built by chromatographers, for chromatographers.

   • Innovative, proprietary, useful features

   • Best-in-class numerical performance
   • Intuitive design and ease of use

Our goal is to dramatically simplify method develoment, and enable far more efficient methods.  We want to improve the way GC method develoment is done around the world!

  1. Temperature & Pressure
    Highly accurate simulations are quickly made in seconds. Up to 99 segments of temperature, 99 segments of pressure programming allowed.
  2. Auto-Optimization
    Unique and powerful Auto-Optimization algorithm quickly provides an optimal separation.
  3. Flow Calculations
    Flow parameters for 3 most common carrier gases- He, H2, and N2. Manually enter pressure program, or simulate constant velocity or flow during a run. Estimate hold-up times.
  4. Animation Viewer
    Novel Animation Viewer provides visualization of a separation as it occurs during a run.
  5. Column Size Effects
    Evaluate effects of different column sizes including length, internal diameter, &/or phase thickness.
  6. Flexible Input
    Simply use 1-3 training runs, depending upon the level of accuracy needed. GC-SOS can use isobaric training runs featuring up to 5 temperature segments.
