I submitted two papers to Proteomics and one to Journal of Proteome Research. Now I wonder if impact factor is a bit misleading in this field.

My question is, isn&#039;t 20 uL a very small volume? Why is there such a huge difference in elution volume between the two spin columns (Desalting v C18 one)?
