Some chapter were really repetitive but a lot of great information. The pictures could have been slightly better. I had some fun moments and some stressful moments but I did learn a thing of two. The wording makes sense but I do understand now to change the strength of the mobile phase and to think in a new perspective.
The book is well organized and simple. It's useful for those who are currently working with HPLC or for those who want to have a theoretical experience and background about method development to help them in writing their articles.
