Packed Capillary LC Columns

Nanofilm capillary coatings are Sepax's patented surface coating technologies that have been developed to coat the capillary tubes with uniform polymer thin films. The polymer film thickness can be well controlled in the range from a few nanometers to a few hundreds of nanometers. The standard Nanofilm coated capillaries have inner diameter (ID) selections of 75, 50 and 25 µm. Our innovative coating process can be readily applied to capillary tubes with inner diameters as low as 15 µm for special applications. Nanofilm coatings include polyacrylamide (PAAm), polyethylene glycol (PEG), PAAm-PEG copolymer and customer-specific coatings. The elimination of non-specific interactions with biological molecules makes Nanofilm coated capillaries ideal for DNA separation and sequencing, protein separation, and protein-protein interaction studies.
