- •
We investigated the effect of PEGs on the structure of monolithic silica capillary columns.
- •
Columns with smaller domain size than previous 2nd generation monoliths were developed.
- •
Improved kinetic performance in the region of N ≤ 40,000 plates is obtained.
- •
Performance improvement is due to smaller domain size and better homogeneity.
