A proprietary surface coating technology was developed for coating the capillary columns. In the process of synthesis, the poly(ethylene glycol) (PEG) brushes are specifically bonded on the silica surface, The PEG film is uniform with thickness in the range of nanometer.

Capillary column:	PEG coated fused silica
Inner diameter:	75, 50, and 25 µm
Coating:	PEG thin film
Coating thickness:	~ 25 nm
Application pH range:	2 - 8.5

• The PEG coating is neutral and hydrophilic
• Extremely high column-to-column reproducibility
• Negligible electro-osmotic flow
• Eliminated non-specific interactions with biological molecules
• Ideal for separations of proteins and other biological molecules
• Suitable for DNA separation and sequencing
