I'm planning to use the SequelPrep Normalisation plate kit to purify and normalise my PCR amplicons for library construction. According to the manual, the kit is able to clean away proteins and short oligo sequences (including the primer dimers which are present in my samples) and other contaminants.

I would like to verify if the plate really does its job in removing the primer dimers and also check the yield after normalisation. But the expected yield (1-2ng/uL) is too low for running on agarose gel. How else can I verify the results?

And is it a common practice to check the end product after the normalisation?
