We discussed the significance of a constant electro-osmotic flow and good capillary conditioning for precision in our CE methods. Now we look at the importance of injection settings for precision. We will also have a first look at sample stacking...

In previous issues we saw the importance of a controlled, constant electro-osmotic flow (EOF) for proper precision. In this issue we will therefore look into the different strategies for capillary conditioning, as a good conditioning procedure is...

The small diameter of the capillary in capillary electrophoresis makes for a very good heat dissipation compared with conventional electrophoresis. As a consequence, much higher voltages can be applied before heat dissipation becomes an issue. 

The selection of the proper background electrolyte (BGE) is key to a successful CE method. We first look into the choices for BGE based on our analyte properties. Capillary electrophoresis (CE) is based on migration of charged components in an...

The capillary electrophoresis (CE)techniques have been around since the 1980s, and commercial instruments available since the end of that decade. So why would we start on such a topic now? There are several indications for a growing interest in...
