short summary of what is going on. In the almost 20 years since its first appearance, Capil­ Writing a monograph like this is a lot of work, even more lary Electrophoresis (CE) has become a standard analy­ than I anticipated. Luckily, I could fall back on the tical separation technique in many laboratories. CE is theoretical and practical experience with CE obtained in now used routinely in applications ranging from in­ our laboratory over the past years. Therefore, I am in­ organic ion determinations to genetic analysis. After the depted to all who contributed to this experience. In the first development studies in R&D groups in the first 10 first place my (former) colleagues Hans Poppe and Jo­ years, and the breakthrough of commercial instruments han Kraak should be mentioned. They started the CE in the second decade, CE has now become a member of work in Amsterdam and teached me a lesson or two the establishment of analytical techniques. This seemed about it later. Together we formed maybe not the most a good moment to summarize the instrumental possibi­ famous but certainly the best-spirited CE research group lities of the technique, its accomplishments and weak in the world. Thanks are also due to the hard-working lab points. The result of this thought is in front of you.
