To use the applet, simply fill in all the boxes and press return or click the calculate button. To change between binary and ternary mixtures, click on the button at the top of the applet display. The default is for a binary mixture. It is also possible to calculate the boiling point of one component of a binary mixture.

When providing quantities, give them in mol, mmol etc, whatever is convenient. They must be consistent, however. All boiling points should be entered at atmospheric pressure.

After the calculate button has been pressed, a graph is drawn showing how the amounts of each component change during evaporation. The x-axis, evaporation extent, is the mole percentage of the initial mixture that has been evaporated.
