WARNING: this is in beta form! Error checking is not complete. This version is a correction over the 4/19/2000 version which had errors for temperature and ionic correction. Results now match the WinMaxc program.

This page should work with ANY machine that has a Javascript enabled browser. Now Mac and UNIX/LINUX users can start to have access to the power of MAXC without need of an emulator. I have tried to keep this page as "browser neutral" as possible. As you can read the source to this page, please feel free to offer suggestions for improvement. [OPEN SOURCE!]. You may also save this page to your computer and use offline with your browser.

IMPORTANT: there is still limited error checking in this version. Be careful how you enter information.
Constants are from the MAXC2.TCM file included with WINMAXC v2.05. View page source to see how the contants are entered into the program. JavaScript cannot read in files of constants, so the constants have to be included nin the program itself. Compare with the MAXC2.TCM text file. Only difference is that chelator names MUST be 7 characters long (pad with spaces). You will only need to edit the constants section to change constants. All values used in the program are read off these lines to fill in the rest of the page [like the ARRAY].

Please feel free to edit and re-use this page as you see fit.
If you post on a web site, I would appreciate a link back to the MaxChelator home page: http://www.stanford.edu/~cpatton/maxc.html


1) Choose a calculation type:


2) Choose temperature in degrees C (0-50), pH (4-10) and ionic strength (empirical ionic equivalents. 0.001-1.000, seawater = 0.5 and ringers = 0.16):

Temperature = pH = Ionic =

3) You must have all cross constants for a calculation to work.
NOTE: Nothing prevents the program from running with unavailable constants, but the results will not be valid!

"A" means constants are available. "T" means temperature compensation is also available.
Enter values to the left of the chelator and metals names you want. All values are in MOLAR. You may use scientific notation, i.e. 1E-3 for 0.001M.

THE ARRAY: [do not edit]



Do not edit chelator or metal names

4) Press CALCULATE to produce answer below: NOTE: you may cut and paste all or parts of the answer to another application.

Gives free and total metals & chelators, Kds, complexes, ionic contribution

NOTE: You can "evaluate chelators" by having a non-zero value for any chelators you wish to evalute [like 1e-6] and at least one metal > zero. Kd's and ranges will appear at end [you may have to scroll down]. Only valid for metal-chelator combinations where there are constants.

Thank you for using WEBMAXC v2.10
