## Abstract An efficient system for preparative reversedβphase separations with packed glass columns is described. The advantage of this system is the use of relatively simple and inexpensive equipment. Column performance, load capacity, effect of the feed volume and the feed concentration on peak

β¦ Synopsis
A rapid method is described for the purification and analysis of synthetic oligonucleotides, based on reversed-phase high-performance liquid chromatography. Volatile buffers and a short column (40 mm X 4.6 mm) packed with Nucleosil 300-5 C4 were employed. Monitoring the column effluent with an UV detector provides an excellent means of controlling product quality. The method is suitable for the purification of crude synthesis products, as well as for desalting and removing gel contaminants from oligonucleotides eluted from polyacrylamide gels. The total time required per sample is less than 25 min.
