ABSTRACT:
Method for opening a high-density packed column in liquid chromatography wherein a large number of components in a solution are separated by means of a column in which a swollen gel is packed at a high density. The improvement involves passing air through the column while heating the column to a temperature above at least 40.degree. C. to shrink the volume of the packed column, and then opening the column. According to this process, there is no loss in the expensive gel nor contamination thereof and yet it's operating efficiency is greatly improved.
