3.7.5 User-Defined Solutes
When selecting the sample solute type it is also possible to select up to four different
user-defined solutes, labelled by default as U1, U2, U3 and U4. These are available by
scrolling through to the end of the list of sample solute types. The table of saturation
constants (or Cs values) of each user-defined solute can be edited by the user. From
the Variables page, to edit your solute, scroll down the solute list and choose one of the
user-defined solutes. Select the solute and it will show the the Cs value editor page.
Each user-defined solute may also be given a customized label which will be appended
to the end of the default labels.
