I am trying to figure out how to get a better quantitation of the gentamicin I am using...only can use an ion exchange column, so I am finding it rather difficult to either get one good peak, or the four seperate isomer peaks with decent enough resolution. I have tried changing flow rate and also changing the gradient a little--any idea how to do this? I also can't change my column at all....kinda stuck...
