Columns of Sephadex G-25, G-15 and G-IO were evaluated under a variety of conditions to determine which provided the most efficient separation of estrogens conjugated with glucuronic acid or sulfuric acid. Elution with 0.01 M ammonium fox-mate of a column of Sephadex G-15 to which had been applied a

The use of the "snake in a cage" amphoteric ion-exchange resin Retardion llA8 for various separations of inorganic ions was investigated. Clean separations of Ga(III)-ln(III)-Tl(IlI), Pt(II)-Pd(JI), and Na(I)-Ni(Il)-Cu(II)-Zn(I1) mixtures have been achieved. In acidic media, in which the resin acts
Hydrophobic anion exchangers were formed by cobonding both ionic and hydrophobic ligands to silica gel. These phases were used to separate single-stranded oligonucleotides and double-stranded DNA restriction fragments. By varying the ratio of n-octyldimethylsilane and either 3-chloropropyldimethylsi
