MAXCHELATOR is a series of programs for determining the free metal concentration in the presence of chelators or total metal given a desired free concentration. Please feel free to copy and give to others. Source code for the math can be seen in the javascript web forms.

Programs of this type are only as good as your environment measurements [ph, temp, ionic, purity] and the constants that you use. There is disagreement on what makes the best constants. Use with caution. Use the program that gives you the best results, even if it is not this one. See Other Programs for other programs hosted or linked to from here.
