H. Gordon et al. in Biochem. Jrnl. 37 79/1 We report new applications and developments of partition chromatography (Martin & Synge, 1941b) in the study of amino-acids and peptides. [Note] We employ the term ‘partition chromatography’ at the suggestion of Dr. E. Lester Smith, to distinguish it from the classical adsorption chromatography. Our earlier term ‘liquid-liquid chromatography’ was liable to confusion with the fractional elution procedure sometimes called ‘liquid chromatography’. 1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) III. 94/2 Volatile, nonpolar substances such as hydrocarbons may be examined by gas adsorption or gas partition chromatography... Weakly polar substances such as alcohols..are examined by adsorption or partition chromatography. 1989 R. Dryer & G. Lata Exper. Biochem. i. vii. 158 To understand the theoretical aspects of partition chromatography, we need only slightly modify the theory just developed for adsorption chromatography. < as lemmas |
