hello GWB, I know this lower temperature database was made available to GWB users by others. However, my interests lie more on the low temperature + organics realm, which makes me gravitate to this database often. I wonder if I can get some help on modifying it. (1) The minteq database does not include the Hydrogen gas. The heading of the database reads: "Visual Minteq does not include H2(g), thus the config->options->"water limits" checkbox for GWB programs Act2 and Tact needs to be unchecked when using this dataset." This suggests there was a reason for the omision, but I was able to include the values from the Thermo database and the water limits are now represented in the plots when using ThermoMinteq as they are when working with the Thermo database. Why was this reaction omitted? (2) I am also at a loss when considering adding an organic compound to the dataset (hydroquinone). I wonder if there are recommendations on where to start or if anyone around has done it. Thanks - MCMA

Hi GWB, I'm doing some simple charge balance type analyses in React. I've encountered an error where I can't bring in my NH3 data using the MINTEQ database. I set the basis species as NH4+, then try to set the units "as NH3 (aq)". That's when I get an error saying "Error: Don't know keyword: (aq)". It seems like it's having trouble interpreting the (aq) in the unit swap (?). Any suggestions on how to deal with this? Thanks, Clark
