Abstract
A simple procedure for the preparation of glass capillary with polar and non-polar stationary liquids, including prior etching and deactivation, is described. A dynamic method of depositing homogeneous solvent films on the capillary walls has been developed. Aspects of the assessment of galss capillary columns are discussed and supplementary proposals for a standardized test procedure with particular regard to temperature stability are made. An improved version of an automated double-column chromatograph for the execution of optimal qualitative and quantitative analyses of aqueous solutins is described.
