A Simple Way to Speed up Separations by GC-MS Using Short 0.53 mm Columns and Vacuum Outlet Conditions

There is a constant drive to speed up GC separations. Shorter analysis times provide more analyses per day, which reduces cost. One approach is to reduce column length and column diameter and columns of 0.15 mm i.d. have indeed grown in popularity. However, the majority of applications are still done with 0.25 mm and 0.32 mm columns.
