Anodic Flow Capillaries
From the earliest days of CE, it was realised that the poor peak shapes which were frequently observed with bases and biomolecules were mainly the result of interaction between the analyte and the capillary walls. Often protein separations were carried out at high pH well above their isoelectric points in order that the wall and the analyte were both negatively charged. The separation of the basic proteins shown in the example below would normally have to be carried out at alkaline pH values in order to try and ensure that the proteins and the capillary wall would be negatively charged.

Anodic Flow Coated Capillaries
The open format capillaries are supplied precut to the required size with the UV window
correctly positioned to fit the specific instrument manufacturer's cartridge system. The capillary
ends are expertly cut to ensure precise sampling.
