Abstract
An add-on batch delivery system for measuring heats of reaction of milligram amounts of solids, liquids and gases with less than 1 mL of liquid in a Calorimetry Sciences Corporation model 4200 calorimeter is described. The system was tested with reactions of dry N2 gas with H2O, HCl(aq) with aqueous tris(hydroxymethyl)aminomethane (tris), KCl(s) with H2O, tris(s) with HCl(aq), Zn(s) with HCl(aq), 2-propanol with H2O, and CO2(g) with NaOH(aq). The precision and accuracy of a single heat measurement is 2–3 mJ or 1–2%, whichever is larger.
