Why do smaller particle size columns improve resolution

Put simply as particle size is lowered efficiency increases and more resolution is achieved In contrast efficiency is directly proportional to the column length (Figure 2) therefore an analyst can keep the same resolution and decrease the length of the column by the same factor as the particle size shortening the analysis time
