I have got a deficiency letter from one authority that wants me to add a column efficiency parameter in the SST of the submitted method (gradient RP-method)
I have replied once that it is not relevant to calculate theoretical plates for a gradient method (this is also clearly stated in the pharmacopeia). But I got everything back with the same request.
Is there another way to evaluate column efficiency than theoretical plates? I would really not like to add this to the method.
