cjacks02 Posted August 14, 2014 Share Posted August 14, 2014 Hello, I am trying to calculate the pe of my water samples but I'm not getting any numbers generated. What inputs do I have to include to get a pe value? Thank You, Chris Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted August 14, 2014 Share Posted August 14, 2014 Hi Chris, You need to constrain the oxidation state of your system in order to calculate a pe value. In GSS, you would need to set the O2(aq) concentration (either the total component, or commonly for DO measurements the free species concentration). Or you can add Eh as a System parameter and use that to calculate pe. In SpecE8, React, X1t, or X2t you have a little more flexibility to constrain the oxidation state. You can set an Eh or O2(aq) concentration like in GSS, or you can swap in a gas, mineral, or species activity ratio to constrain the oxidation state. Hope this helps, Brian Farrell Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
