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 114°C. A 300 meter glass column (0.25 mm i.d.) which is etched, coated with a mixture of normal hexadecane and Kel‐F10157 is utilized to perform this separation at room temperature. The separations obtained with this non–polar liquid mixture and the «inert» glass surface are much more rapid than those previously obtained with stainless steel capillary columns.

## Abstract Triglycerides are separated according to their molecular weight and their degree of unsaturation on glass capillary columns by use of the on‐column injection technique. The columns employed are silylated SE‐30 columns of 4.5, 8, and 10m length with a film thickness of ca. 0.15 μm. The p

Both packed and open-tubular capillary columns are employed in supercritical fluid chromatography (SFC). The advantages and disadvantages of these columns in SFC have been discussed [l-31. Further discussions seem appropriate to predict which type of columns will survive in SFC. Fused-silica capilla
