Microextraction for HPLC December 2 2014 Chris Peery Outline Introduction Theory AdvantagesDisadvantages Applications Conclusions Introduction Context Most pesticides are organic compounds with various functional groups which may cause geometrical and optical isomers. Positive deviation of the enthalpy of mixing and consequently limited solid solubility may be predicted from known atomic properties.. Hume-. Rothery. - empirical rules to predict solid solubility. For solid solubility exist b/t two elements, the following settlements are always true:. Multicomponent Phase Equilibria. Raoult’s Law .
