Webcolumn efficiency, than columns with a lower plate count. A column with a high number of theoretical plates will have a narrower peak at a given retention time than a column with a lower N number. High column efficiency is beneficial since less peak separation (meaning lower alpha, α) is required to completely resolve narrow peaks. WebQ How do I best evaluate the efficiency of column regeneration (the restoring of column binding capacity)? A We recommend to do a dynamic binding capacity test (e.g., at 10% breakthrough) with a known protein. Do that test when the column is new, to have a baseline of the binding capacity, and repeat the test after usage/ column regeneration.
