This is an example of a Murashige-Skoog Basal Medium which has been entered into the Geochem-EZ interface. Notice that there are dropdown boxes for the entering the salts, or ions interest. This dropdown list can be easily customized. Concentrations can be entered either as weight per volume (e.g., g/ L) or in molar units.

The program allows the user to consider or disallow precipation, mixed solids, redox reactions, and CO₂ partial pressure. It will calculate the ionic strength and the pH of the solution given the required inputs. Multiple cases can be run. Here there are two cases (M-S basal, can ppt) being analysed in this run. This is very helpful if one wants to see how varying a parameter (e.g., pH, ion concentration) will affect the ions of interest in the experimental solution.
