History of Planar Chromatography
TL;DR: In this article, it was shown that IR spectroscopy and spectrometric methods are incapable of carrying out complete analysis of complicated mixtures, as a consequence, the individual substances must be separated from one another before spectrophotometric determination can take place.

Mobile phases in liquid chromatography
R. J. Hamilton,P. A. Sewell +1 more
TL;DR: In Chapter 4, many different stationary phases were described which are now available commercially and it must be stressed that the suitability of any stationary phase in LC depends on the mobile phase with which it is used; e.g. Durapak columns must not be used with aqueous solvents.

Lester Yoder,Byron H. Thomas +1 more
TL;DR: Adsorption columns of floridin, alumina, and silicic acid were used to study their capacities to concentrate the antirachitic activity in sulfonated cholesterol or two of its derivatives as mentioned in this paper.
