  Othmer method vapor/liquid equilibrium
measuring apparatus

This apparatus is for taking data of two substances' based on Vapor-liquid equilibrium. The data is for making xy equilibrium chart.


                                        < How to use and How to operate >
  1. x and y are Mole fraction of low boiling point components in liquid phase and gas phase.
  2. When two substances are heated to reach at equilibrium state, measure the components of liquid phase and vapor phase. You could get x (liquid phase) and y (vapor phase) point for the chart from gas chromatography result.
  3. To change composition ratio you could get some more x, y points for complete chart.
  4. This apparatus has jacketed column to reduce influencing from outside temperature.
