摘要
A method and apparatus for enabling larger injection volumes and for reducing extra column effects in chromatographic separations using focusing pre-columns placed upstream of the analytical, or preparative, column with applications in any chromatographic system where the requirement is that the focusing pre-column, placed upstream of the analytical column, allows larger injection volumes to be utilized and, by enabling efficient focusing of solutes onto the analytical column, results in a significant reduction of band broadening due to extra-column effects which act upstream of the analytical column.
