A nonaqueous packed capillary electrochromatographic reversed-phase separation method for retinyl esters has been developed. The best performance was obtained using a 180-m-i.d. column packed with 3-m Hypersil ODS and a mobile phase consisting of 2.5 mM lithium acetate in N, N-dimethylformamideα Ε½ .
## Abstract Techniques have been developed for the rapid separation (about 20 minutes) of the 39 compounds in crude petroleums, or petroleum distillates, which boil between 28 and 114Β°C. A 300 meter glass column (0.25 mm i.d.) which is etched, coated with a mixture of normal hexadecane and KelβF101
