Extraction Chromatography (cont)<br />
• The term extraction chromatography is used if<br />
the stationary phase is an organic liquid and the<br />
mobile phase an aqueous solution.<br />
• EXC couples the selectivity of the extractants<br />
used in liquid-liquid extraction with the multistage<br />
character of a chromatographic process.<br />
• This method now provides a favorable<br />
alternative to ion exchange for many analytical<br />
separations.<br />
