Binding of cyclic compounds by starch cryotextures from aqueous solutions
Binding of cyclohexanol, 2-, 3-, and 4-methylcyclohexanones, and isomeric fenchone and camphor bicycles by the corn starch cryotextures from aqueous solutions in a concentration range of 1—16 mmol L–1 was studied...

Sorption of aliphatic ketones from aqueous solutions by starch cryotextures
Capillary gas chromatography was applied to study the sorption of aliphatic ketones (C6—C11), including metamers, from aqueous solutions by corn starch cryotextures. The amount of ketones sorbed by cryotextures d...

Peculiar features of sorption of positional isomers of formyl-, acetyl-, and aminopyridines in capillary gas-liquid chromatography
The GLC retention parameters of α-, β-, and γ-isomers of formyl-, acetyl-, and aminopyridines were determined on two columns with stationary phases of different polarities. The contributions of formyl, acetyl,...

Flaked capillary columns with crown ether complexes for gas-liquid chromatography
Flaked capillary columns with an OV-101/CE-Na{in3}PO{in4} hydrophobic-hydrophilic sorbent have been suggested. This sorbent provides for the analysis of polar and nonpolar substances, including amines and amin...
