The novel PEG/PAAm block-copolymer structure is a patented technology. Both PEG and PAAm coatings have very good resistance to nonspecific bindings with biological molecules. This novel structured coating will allow extremely reproducible separations, even though some degradation of PAAm coatings occur during the process of the separation. The great advantage of the PEG/PAAm block coating is that it achieves unprecedented separations for biological molecules. It is a combination of high efficiency separation with great stability and reproducibility for capillary electrophoresis.

Capillary column:	PEG/PAAm coated fused silica
Inner diameter:	75, 50, and 25 µm
Coating:	(1) PEG thin film, ~25nm (2) PAAm thin film, ~20nm
Application pH range:	2 - 9

• The PEG/PAAm coating is neutral and hydrophilic
• Extremely high column-to-column reproducibility
• Coating stability: extremely high
• 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
