I was wondering if anyone has any knowledge, or experience, with Charged Surface Hybrid (CSH) columns; specifically with respect to equilibration time.
As the name implies, these columns have some charge on the surface, and there are some benefits to this.
In their literature they actually claim faster equilibration with respect to changes in pH. But what I'm wondering about is the typical equilibration that happens at the end of a run, when the system is going from high organic back to low organic. I am suspecting that this type of equilibration may take longer with a CSH column, and so was wondering if anyone has had any similar observations.
Thanks very much, in advance.
