Downloads and Web Programs

Web versions that are easy to change constants in. Slight differences in answers are the result of rounding errors in calculations. Javascript is not double precision.

Single Chelator Metal Calculators

MgATP - Free, Total, Bound and Total ATP, constants from NIST database #46 v8 (25°C, 0.1N)

MgATP - Free, Total, Bound and Total ATP, constants from 'Chelator' program (37°C, 0.165N)

CaEGTA - Free, Total, Bound and Total EGTA, constants from NIST database #46 v8 (25°C, 0.1N)

CaEGTA - Free, Total, Bound and Total EGTA, constants from 'Chelator' program (37°C, 0.165N)

Two Chelator, two metal calculators

CaMgATPEGTA - Free & Total, constants from NIST database #46 v8 (25°C, 0.1N)

CaMgATPEGTA - Free & Total, constants from 'Chelator' program (37°C, 0.165N)

EXPERIMENTAL: Two Chelator, two metal calculators w/ pH plot [may not work with IE browser]

CaMgATPEGTA - Free & Total, constants from NIST database #46 v8 (25°C, 0.1N)

CaMgATPEGTA - Free & Total, constants from 'Chelator' program (37°C, 0.165N)

If you are unable to deal with the source code for the above pages I will endeavor to create a version with whatever metals/chelators/constants you need, assuming constants are available.

Older Web Maxc versions Standard and Extended and the Lite version [Ca,Mg, ATP, EGTA) constants from Bers and from NIST database, adapted to 20°C, 0.1N

Calculator for pH buffers WEBBUFCALC - Good buffers: ionic concentration contribution helper program.

Windows Maxc program winmaxc32.zip v2.51 constants from NIST database, adapted to 20°C, 0.1N
