Analogous to ion chromatography, CCC can separate both inorganic and organic ions according to their pKa of affinity to the ionic ligand dissolved in the stationary phase. One example is illustrated in Figure 8, which shows separation of rare earth elements by pH gradient elution of a hydrochloric acid mobile phase through a hexane stationary phase containing a ligand, di-(2-ethylhexyl)phosphoric acid. Figure 9 is another example showing the separation of catecholamine. The left chromatogram, obtained with a ligand-free solvent system, shows no sign of separation (Figure 9A). When a basic ligand, triethylamine, is added to the stationary phase, all components are resolved (Figure 9B).

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming.
