Web12.1.2 A Better Way to Separate Mixtures. The problem with a liquid–liquid extraction is that the separation occurs in only one direction—from the sample to the extracting phase. Let’s take a closer look at the liquid–liquid extraction of an analyte and an interferent with distribution ratios of, respectively, 5 and 0.5. WebThe analyte concentration is transduced into a detectable signal, generally by using potentiometric or amperometric methods. Potentiometric electrodes measure the equilibrium potential between an...
