Lot-to-lot Selectivity Test

An example of an evaluation method is the chromatogram of the selectivity test. The degree of separation of components 4 and 5 indicates the strength of the hydrophobic interaction of the filler and the resolution of components 6 and 7 indicate the stereo selectivity of the filler. We unexpectedly evaluate and inspect these columns from various angles to provide stable HPLC columns.
