Because fused silica tubing has a smoother interior surface than stainless steel, fused silica columns might offer slightly higher efficiencies for phase films of less than approximately 1 micron. For film thicknesses greater than 1 micron, there will be very little difference in efficiency between fused silica columns and MXT columns.
Are fused silica (FS) capillary columns superior to MXT stainless steel columns? If so, why?
