"One excellent point from Agilent is the booklet inside the box and with all information regarding the column is clearly described. In terms of capacity of separation, this column is really excellent but the biggest problem of this column is its’ lifetime. Only after less than 1000 of injections of clean samples (plasma or buffers extracted by SPE for example), the peak shape deteriorates very quickly i.e a lot of tailing. This happens several times even when using an in-line frit before the column. Even after a thorough cleaning of the column, you will not be able to get back a good peak shape. By comparison with columns from the competitors, similar columns from Waters (Acquity) and from Phenomenex (Kinetex) are much better alternatives, especially if you just check the price. For the same amount of money, you will be able to inject 3-5 times more on Waters and Phenomenex columns."
