Simple, multibore columns for superior fractionation of lipids

Multibore columns were constructed and found to have a high capacity, give sharp resolution, with less adsorbent and smaller amounts of eluting solvent. A separation requiring 12 hr on a straight column can be accomplished in one-third less time on a multibore column. This factor, added to the superiority of fractionations on multibore columns, has proved to be of great benefit in routine analysis.
