How to find all combinations of a variable?

Jun 8, 2023 02:11 PM (583 views)

Hi! I need to be able to find combinations of a variable that equals a certain number. For example, I have a list of 5 solvents all with different solubility parameters. I need to be able to identify what combination of solvents would equal a solubility parameter of approximately 10 (Ex. 30% solvent A + 70% solvent B = solubility parameter of 10.05).  Any ideas om how to achieve this?

You can specify such a linear combination as a column formula using the separate solvent data columns. You can add the Response Limits column property to this Solubility column. Use a Match Target for this property. Then launch the Graph > Profiler on the formula column to solve for the desired value.
