# WEBMAXC STANDARD

7/3/2009 see WEBMAXC EXTENDED for more metals

**NOTE: It is possible with the FIND FREE METAL calculation to produce answers that are not valid. This is more likely to occur with multiple metals. If you find one of the metals shows almost no effect of the chelator presence, be suspicious. Try different concentrations of the second metal. If there is a point where the result suddenly changes the first metal, then you are having problems with a convergence error. Try the Windows version. Here double precision math is used and it is also able to warn specifically about convergence problems.**

### PROGRAM

1) Choose a calculation type:

**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.

Calculations above the buffer range of a metal/chelator can result in a convergence error in Find Free mode.
